Stretch Four in Basketball: The Shooting Big Explained

Game 1 of the 1991 NBA Finals, Chicago Stadium, the closing seconds. The Los Angeles Lakers trailed by two when Magic Johnson moved the ball to Sam Perkins, a 6-foot-9 forward, out beyond the three-point line. Perkins made the shot, Byron Scott split a pair of free throws, and the Lakers won 93-91. A power forward had decided a Finals game from beyond the arc.
That is the whole idea of a stretch four. A stretch four in basketball is a power forward who makes three-pointers often enough, and accurately enough, that the man guarding him has to leave the paint and follow him to the arc. The defender is usually a big man whose job is to protect the rim, so every step he takes toward the shooter is a step away from the basket. The term is NBA slang rather than a rulebook position: the stretch four still plays the 4, still guards big men and still rebounds, but on offense he spaces the floor instead of posting up.
What a stretch four in basketball actually is
Start with the numbering. Coaches label the five spots on the floor 1 through 5, from the point guard to the center, and for most of the sport's history the 4, the power forward, worked inside: setting screens, posting on the block, crashing the offensive glass. Our guide to the power forward position and how it moved from the post to the arc covers that older job in detail. The stretch four is what happens when the person in that slot can shoot.
The definition turns on the defense, not the shooter. A forward who takes a few threes a night that nobody respects is not stretching anything. His defender sags into the lane, ignores him, and waits to block somebody else's layup. A forward becomes a stretch four at the moment the opposing coach decides that leaving him open is worse than leaving the rim unguarded.
That decision rests on two numbers: how often the player shoots and how often the shots go in. Volume matters because a defense will gamble on a big man who takes two threes a game, figuring the odds favor them over 48 minutes. Accuracy matters because a shooter who makes 30 percent from deep is giving the defense a good trade every time he is left open.
The physical profile
There is no height requirement. The classic stretch four is somewhere between 6-foot-8 and 7 feet, long enough to defend other big men and rebound in traffic, with a shooting stroke that holds up from the corners and the top of the arc. Dirk Nowitzki, the role's most decorated player, was listed at 7 feet. Robert Horry, who did it in a smaller frame, was listed at 6-foot-10.
What separates the stretch four from a tall wing is the other end of the floor. He is expected to guard power forwards and sometimes centers, to box out, and to protect the defensive glass. A 6-foot-8 shooter who cannot do those things is a small forward playing up a position, which is a different arrangement covered further down this page.
What the label does not mean
It does not mean the player only shoots threes. Nowitzki scored most of his points inside the arc, many of them on a one-legged fadeaway from the elbow. It does not mean a lack of toughness either. Kevin Love, a stretch four on Cleveland's 2016 title team, had been one of the league's best rebounders in Minnesota. The label describes one skill that changes what the defense can do, and it says nothing on its own about the rest of the player.
What gets stretched: the rim protector and the empty lane
Picture the floor from above. A standard NBA defense keeps its tallest player near the basket, not because a rule makes him stand there but because that is where shots are most valuable. Layups and dunks go in far more often than any jump shot, so the defense's whole structure exists to keep the ball out of the restricted area under the rim.
Now move the man he is guarding. If the opposing power forward or center stands at the three-point line, 23 feet 9 inches from the basket at the top of the arc and 22 feet in the corners, his defender has a choice. He can stay home in the lane and give up an open three, or he can follow his man and leave the paint without its last line of protection.
NBA rules close the obvious loophole. Since the 2001-02 season, when the league legalized zone defenses, a defender may not stand in the lane for more than three seconds unless he is actively guarding an opponent. The defensive three-second violation means a big man cannot simply park under the rim while his assignment stands outside. He has to be within arm's length of his man or keep moving in and out of the lane, and that small rule is a large part of why floor spacing works the way it does in the professional game. College basketball has no defensive three-second rule, which is one reason a college center can sit deeper in the paint against a shooting big.
Who benefits
Every other player on the floor. A guard driving off a screen meets no shot-blocker waiting at the rim. A wing cutting backdoor finds an open lane. A post player on the block gets single coverage because nobody is free to double him from the weak side. The stretch four may score only a dozen points and still be the reason his team's guards shot well at the basket that night.
This is why coaches describe stretch bigs in terms of gravity, a borrowed word for the pull a shooter exerts on defenders who cannot leave him. A good shooting big has gravity in a specific direction: away from the hoop, which is exactly where the defense least wants to go.

The two arc figures are measured from the center of the basket; the rim height is from the floor and the lane figure is the width of the free-throw lane. The NBA shortened the line to a uniform 22 feet from 1994-95 through 1996-97 and then restored the original arc.
The pick and pop and why it breaks drop coverage
The most common action in the NBA is a ball screen: a big man sets a pick on the ball handler's defender, and the two attackers play two against two. In the traditional version the screener then rolls toward the basket, and our explainer on the pick and roll covers the many reads that follow. In the pick and pop, the screener does the opposite. He steps back, or sideways, to an open spot behind the arc and waits for the pass.
Against most coverages that is a small variation. Against drop coverage it is a direct attack on the scheme's central assumption.
What drop coverage asks of the big man
In a drop, the screener's defender retreats toward the paint as the screen is set, sitting somewhere around the free-throw line or lower. His job is to wall off the drive and the roll at the same time while the guard's defender fights over the top of the screen to recover. Drop coverage is popular because it keeps a center near the rim and concedes the shot defenses like best: a pull-up two from the mid-range. The site's guide to drop coverage explains the full mechanics.
The weakness is obvious once the screener can shoot. The big man in the drop is moving toward the basket. The stretch four is moving away from it. After two or three steps they are 20 feet apart, the ball handler is coming off the screen with the ball, and a simple pocket pass or skip pass finds the popper with nobody near him.
- The screenThe stretch four sets a ball screen at the top of the floor on the guard's defender.
- The dropHis own defender sinks toward the free-throw line to guard against a drive or a roll to the rim.
- The popInstead of rolling, the screener steps out to an open spot beyond the arc, usually at the top or on the wing.
- The decisionThe ball handler reads the dropping big. If he stays deep, the pass goes to the popper.
- The shot or the driveIf the big runs out to the shooter, the lane behind him is empty and the ball handler attacks the rim.
A typical sequence in the NBA half court. Defenses adjust in real time, so a well-drilled team may switch or blitz before step four is reached.
The two-way squeeze
The best pick-and-pop players turn the play into a choice between two bad options for one defender. If he stays in the drop, the screener shoots an uncontested three. If he jumps out early to take away the shot, the ball handler turns the corner and has a clear path to the basket. A center who must guard both at once ends up guarding neither well.
Nowitzki and Steve Nash ran this in Dallas around the turn of the century, and defenses learned that the usual rules did not apply. Rashard Lewis and the Orlando Magic ran a version of it later in the decade. By the 2020s almost every NBA roster held at least one big man capable of popping, which is the clearest sign of how completely the stretch four changed the play.
Stretch four versus stretch five: moving the idea to center
The same tactic works one position over. A stretch five is a center who shoots threes, and when he does it the effect is larger, because the player he drags to the perimeter is usually the other team's main rim protector.
Here is the difference in plain terms. Against a stretch four, the defense still has a center in the paint. The stretched defender was a helper, and losing him hurts, but somebody remains between the driver and the basket. Against a stretch five, the defender pulled out to the arc is that somebody. If the opposing center follows his man, the paint can be empty of anyone taller than 6-foot-8.
| Feature | Stretch four | Stretch five |
|---|---|---|
| Lineup slot | Power forward, the 4 | Center, the 5 |
| Defender he pulls out | Usually the opponent's power forward | Usually the opponent's main rim protector |
| What the defense still has inside | A center near the basket | Often nobody taller than a forward |
| Defensive burden on the shooter | Guard forwards, help from the weak side | Protect the rim, anchor the defense |
| How common in the NBA | Standard by the late 2010s | Rarer, though increasingly common |
Why shooting centers are scarce
Two reasons. First, the jobs pull in opposite directions. A center is asked to protect the rim and rebound, which demands size and strength, and players with that body type have historically been coached to work near the basket from a young age. Learning a reliable three-point shot takes thousands of repetitions that a big man in a youth program rarely spends at the arc.
Second, a stretch five has to survive at the other end. A center who shoots but cannot defend the basket gives back on defense most of what he creates on offense. That combination of rim protection and perimeter shooting in a 7-footer is so unusual that it shapes contract markets and draft boards.
Brook Lopez is the best-known example of a center rebuilding his game to fill the role. He took almost no threes for most of his first eight seasons with the Nets, then turned into a high-volume three-point shooter from 2016-17 onward, and later anchored the defense of Milwaukee's 2021 title team as a center who also spaced the floor. Al Horford made a similar late shift in his career and was part of Boston's 2024 championship rotation. Players such as Karl-Anthony Towns and Kristaps Porzingis arrived in the league with the shot already built in. More on the full job at the five is in our guide to what a center does at both ends.
How good the shooting has to be before the defense stops helping
No number in the rulebook marks a player as a stretch four. The threshold lives in the opposing coach's scouting report, and it moves with what that coach is trying to protect.
The arithmetic is still a useful starting point. A three-pointer that goes in 34 percent of the time is worth about 1.02 points per shot. A two-pointer has to go in 51 percent of the time to match that. Most of the shots a defense gives up by helping off a big man are threes, so the question the defense is really asking is whether that shooter, on that shot, beats the value of the drive or the post-up the help is stopping.
Accuracy
League-wide three-point accuracy in the NBA has sat in the mid-30s in percentage terms for decades, even as the number of attempts exploded. A big man who shoots around that level on a meaningful volume is generally guarded. One who shoots in the high 30s gets a defender running at him hard. Below about 32 percent, many defenses will help off him and live with the result, particularly in the playoffs, where scouting is sharper and every possession counts more.
Volume
The less obvious half. A player who makes 40 percent of his threes on one attempt a game is not yet a threat the defense must respect, because the sample is small and his own team plainly does not trust the shot. Defenses read hesitation. A big man who passes up an open three, or pump-fakes and drives into traffic, tells the other bench that he can be left alone.
This is why coaches of developing stretch bigs often insist on volume early, even at a poor percentage. The goal is to make the shot automatic so the defense has to account for it.
Shot type
A stretch four's threes should mostly be catch-and-shoot attempts, taken in rhythm off a pass. A big man who needs to dribble into his shot is a different, rarer kind of player. The two shot types also tend to land at different percentages league-wide, with catch-and-shoot attempts going in more often.
What a stretch big costs his team
Nothing on a basketball court is free. A big man who stands at the three-point line on offense is not near the offensive glass when the shot goes up, not on the block when a guard needs an outlet, and often not the physical presence that the role used to demand.
Offensive rebounding
The most direct cost. Offensive rebounds come from players who are near the basket when a shot misses. A power forward spotting up 24 feet away is out of that picture by design. Teams that play two stretch bigs together usually give up second-chance points they used to collect, and plenty of NBA coaches have accepted that trade knowingly, sending players back on defense instead of crashing to guard against transition baskets.
Post scoring
A stretch four who lives behind the arc is not posting up, which removes an option from late-clock possessions and from games in which the jump shots are not falling. The best versions, Nowitzki above all, kept a post game and used the threat of the three to make it harder to guard. Many lesser stretch fours did not. On a cold night those players have nowhere else to go, and a defense can play them straight up because it knows what is coming.
Rim protection
This is the hidden cost, and it shows up on the other end. Teams that prized shooting at the 4 and 5 often accepted big men who were slower to rotate, shorter, or less effective as shot-blockers. A lineup with two stretch bigs may have no real rim protector at all, which pushes the burden of help defense onto wings and guards.
Read the chart one way and the case for the stretch four is overwhelming: a big man who shoots 38 percent on threes produces more per shot than almost any post-up. Read it the other way and it shows why a poor shooter at the 4 is so costly. A 30 percent three-point shooter is no better per attempt than a 45 percent two-point shooter, and he gives up the rebounding and post work as well.
How defenses answer a shooting big
The first answer is the simplest. Switch.
Switching a smaller player onto the shooter
Modern NBA defenses switch many ball screens, swapping assignments so that each defender picks up whichever attacker is in front of him. Against a pick and pop, that puts the guard's defender on the popping big man and the big defender on the ball handler. The shot is contested. The cost is a mismatch, often a 6-foot-3 guard on a 6-foot-10 forward, which the offense will try to punish by posting the big man up. The tradeoff is size for contest, and coaches make it every night.
Switching only works if the stretch four cannot punish a small defender inside. Many could not, which is why switching spread so quickly through the league in the 2010s.
Closing out late
The second answer is to help off the shooter anyway and rotate back as the pass is thrown. A defender sprinting at a shooter is in a weak position, moving forward with his weight committed, so the shooter can pump-fake and drive past him. That is why the stretch four who can put the ball on the floor for one or two dribbles is worth more than the one who cannot. A late closeout becomes a drive to the basket, and the defense has lost twice.
Daring the big to score inside
The third answer is a judgment about the player. If a stretch four's only weapon is the three, the defense can assign a quicker, smaller defender to chase him off the arc and dare him to beat that defender in the post. Plenty of shooting bigs struggled against that tactic, especially in the postseason, when teams have days to prepare for one opponent.
The best stretch bigs beat all three answers by being more than shooters. Nowitzki punished switches with his fadeaway. Horry made the timely shot and also defended the post. The ones who could only shoot tended to lose minutes as the playoffs went deeper.
Stretch four versus small-ball four
These two lineups are often confused, because both put a shooter at power forward. They come from opposite directions.
A stretch four is a big man who learned to shoot. He has a frontcourt player's size and defends like a frontcourt player, and his outside shot is the addition.
A small-ball four is a wing who moves up a position. He is usually a small forward, sometimes a large guard, slotted into the power forward spot so a team can put more speed, ball handling and switchability on the floor. He shoots because wings shoot. His challenge is guarding players bigger than he is and holding up on the defensive glass.
| Trait | Stretch four | Small-ball four |
|---|---|---|
| Natural position | Power forward or center | Small forward or wing |
| Typical size in the NBA | 6-foot-9 to 7 feet | 6-foot-6 to 6-foot-8 |
| Strength on offense | Spacing, pick and pop | Handling, passing, driving |
| Strength on defense | Size against bigs, rebounding | Switching onto guards and wings |
| Main weakness | Foot speed on the perimeter | Size against post-ups and on the glass |
| Lineup it usually anchors | Traditional big-plus-four frontcourt | Lineups with one big or none |
Where the two overlap
Golden State's small lineup of the mid-2010s, with Draymond Green at center and wings around him, is the best-known small-ball arrangement. Green himself was an undersized power forward rather than a wing, and his value came from passing, switching and defense more than shooting, which shows how loosely the labels fit real players. The wider argument that positions no longer mean much is in the guide to positionless basketball.
The practical test is simple. When the opponent posts up the 4, does the defender hold his ground? A stretch four usually can. A small-ball four often needs help.
How to spot a stretch four on the stat sheet
Box scores were not built to identify this role. Points, rebounds and three-pointers made say little about whether a big man is pulling defenders out of the lane. A few numbers do a better job.
Three-point attempt rate
The cleanest single indicator. Three-point attempt rate is the share of a player's field-goal attempts that are threes: three-point attempts divided by total field-goal attempts. A traditional big man might have a rate near zero. A committed stretch four will often have a rate above 40 percent, meaning four or more of every ten shots come from deep. The rate measures intent. It tells you where his coach has placed him on the floor, independent of whether the shots are falling.
Catch-and-shoot share
Since the NBA installed optical player-tracking cameras in every arena for the 2013-14 season, the league has published how many of each player's shots come on a catch with no dribble. For a stretch four this share is usually very high, because his threes arrive off passes from the ball handler he screened for or off kick-outs from drives. Those tracking splits are the quickest way to separate a spacer from a big man who creates his own shot.
Shot location
Shot charts reveal a pattern quickly. The stretch four's attempts cluster in two places: at the rim, from cuts and putbacks, and beyond the arc, especially at the top and on the wings where pick-and-pop actions end. The mid-range between them is often nearly empty. A big man whose chart is dense in the corners is more likely a spot-up specialist. One whose chart is dense at the top of the key is popping out of screens.
Efficiency measures that include threes
Field-goal percentage undervalues shooters because it counts a made three the same as a made layup. Effective field-goal percentage adjusts by giving threes their extra half-point of credit, and true shooting percentage folds in free throws as well. A stretch four with a modest raw percentage may look much better once those adjustments are made, which is why the adjusted figures belong next to any shot chart.
| Number | What it measures | What it says about a stretch four |
|---|---|---|
| Three-point attempt rate | Share of shots taken from three | How often he is placed at the arc |
| Three-point percentage | Share of threes made | Whether the defense must respect the shot |
| Catch-and-shoot share | Share of shots taken without a dribble | Whether he is a spacer or a creator |
| Shot chart location | Where on the floor he shoots | Pick and pop at the top or spot-ups in the corners |
| Offensive rebound rate | Share of available misses he grabs | How much crashing he has given up |
Big men who shot from outside before the term existed
The NBA did not adopt the three-point line until the 1979-80 season, so the earliest shooting big men were stretching defenses with long twos. The effect was the same in kind, smaller in degree.
Bob McAdoo
McAdoo was the prototype. Playing center and forward for the Buffalo Braves in the 1970s, he won three straight scoring titles and the 1974-75 MVP award while shooting smooth jump shots from 15 to 20 feet, an unusual range for a player his size at the time. Defenders who were used to guarding big men on the block had to follow him out. Late in his career he came off the bench for the Showtime Lakers and won championships in 1982 and 1985. He was elected to the Naismith Memorial Basketball Hall of Fame in 2000.
McAdoo predated the three-point line in the NBA, so none of his peak work involved threes. What he showed was that a big man's jump shot could reorganize a defense.
Bill Laimbeer
Detroit's center during the Bad Boys era shot from outside in a way that infuriated opponents almost as much as his physical play. Laimbeer was not a high-volume three-point shooter by modern standards, but he was willing to take the shot as a center at a time when almost nobody at that position did, and he did it on teams that won the NBA title in 1989 and 1990. Defenders who had to respect his jumper were not free to clog the lane against Isiah Thomas and Joe Dumars.
Sam Perkins
Perkins, nicknamed "Big Smooth," is the bridge between the old game and the new. A national champion at North Carolina in 1982 alongside Michael Jordan and James Worthy, he spent 17 seasons in the NBA with Dallas, the Lakers, Seattle and Indiana, and his three-point shooting grew more central the longer he played. His game-winner in the 1991 Finals came in an era when a 6-foot-9 forward taking that shot still surprised people. By the time he reached Seattle and Indiana in the 1990s, Perkins was being used as something close to a modern stretch four.
None of the three was called a stretch four. The phrase came later, once teams began building rosters around the idea.
The players who made it a job title
Robert Horry
Horry won seven championships, with Houston in 1994 and 1995, the Lakers from 2000 through 2002 and San Antonio in 2005 and 2007. He was never the best player on any of those teams. What he did was play the power forward spot while standing at the three-point line, defend bigger players adequately, and make shots at moments when his team needed them.
Two of those shots are still replayed. In Game 4 of the 2002 Western Conference finals against Sacramento, Vlade Divac tapped a loose ball out toward the top of the key and Horry hit a three at the buzzer for a one-point Lakers win. In Game 5 of the 2005 Finals at Detroit, Horry scored heavily over the fourth quarter and overtime and hit the three that won the game. His nickname, "Big Shot Rob," described the role as well as any scouting report.
Rashard Lewis and Orlando's four-out offense
Stan Van Gundy's Orlando teams of the late 2000s were built around a simple principle. Put Dwight Howard, a dominant interior center, near the rim and surround him with four players who could shoot. Rashard Lewis, a 6-foot-10 forward, was the most important of the four, because he played the position where an opponent would normally have a second big man ready to help on Howard.
When Lewis stood at the arc, that second big man had to stand with him. Howard got single coverage. Guards got driving lanes. In 2009 the Magic beat a 66-win Cleveland team in the Eastern Conference finals and reached the NBA Finals, where they lost to the Lakers. Orlando made the four-out formation look like a system rather than a gimmick.
Dirk Nowitzki
Nowitzki is the reason the label stopped sounding like a compromise. A 7-footer from Germany who joined Dallas in a 1998 draft-night trade, he spent all 21 of his NBA seasons with the Mavericks and became the model for every tall shooter who followed.
He won the 2006-07 MVP award in a season in which he shot better than 50 percent from the field, 40 percent from three and 90 percent from the line. In 2011 he led Dallas past Miami in the Finals and was named Finals MVP. Nowitzki was not a spot-up specialist. He created his own shots, punished switches in the post and drew constant attention. But his range at 7 feet forced every opponent to reconsider how it defended the 4, and after Dallas won the title, more teams began searching for their own version.
From specialist to default: the rise of the shooting big
In the first NBA season with a three-point line, teams averaged under three attempts a game. By 2019-20 the figure was above 34. Some of that increase came from guards and wings, but a large share came from big men who, a generation earlier, would never have been allowed to shoot from that range.
League-wide averages per team per game, rounded, at four sample seasons. The figures cover all positions and are not specific to power forwards or centers.

Why it accelerated in the 2010s
Several changes landed together. Analytics departments made the case that corner threes and shots at the rim were the most efficient attempts, and that long twos were the worst. Tracking data showed how much spacing affected the success of drives. Golden State's run of titles from 2015 onward, with shooters everywhere, made the approach look inevitable, and coaches across the league copied what was winning. The broader shift is traced in our article on how the three-point line changed basketball.
Rule changes also played a part. The ban on hand checking on the perimeter in 2004-05 made drives harder to stop, and drives work better when the lane is empty. Shooting bigs empty the lane.
The non-shooting four as the exception
By the late 2010s and into the 2020s, a power forward who could not shoot threes had become a liability that teams worked to hide. Some still started and won, usually because they were exceptional defenders or rebounders. But the default expectation at the 4 had reversed. Where once a power forward who shot from outside was a novelty, the novelty became the power forward who did not.
What remains of the label
Because nearly every NBA big man now shoots at least a little, the phrase "stretch four" is used less than it was in 2010. In some sense the role won so completely that it no longer needs a separate name. The idea survives in scouting language and in college basketball, where shooting bigs are still less common and still a matchup problem in the NCAA Tournament. For the rest of the cluster on how positions and lineups fit together, the basketball hub gathers the site's coverage of the sport.
