Every coach has watched a team get beaten by back cuts and thought, "we knew that was coming." That's the Princeton offense in one sentence. The defense knows. The cut still works, because the spacing is built so that a defender who overplays has nothing behind him, and the player with the ball is a center standing at the elbow who sees the whole floor.
Every play in this guide lives in the Princeton section of the Play Bank, where you can step through all twelve in one place.
I spent a good while learning this one properly before I drew it, because it's an offense a lot of coaches ask about and not many explain well. The plays below come from Pete Carril's own clinic notes, Lisa Thomaidis's Canadian national team playbook, and the coaches who teach it now, Hooper University and Lee DeForest most of all. I've drawn each action as its own animated play against a live defense, so you can see the read, not just the route.
What Princeton is, and why it still works
Pete Carril coached Princeton from 1967 to 1996, won thirteen Ivy League titles, and led the country in scoring defense nineteen times with teams that had no business doing either. He didn't like the name "Princeton offense." He often said the ideas came from Red Auerbach's Celtics: the weave, the handoff, and a center who played above the free-throw line instead of on the block.
Here's how it lines up. Four perimeter players who can all pass, dribble, and shoot. One center who catches at the elbow, pivots, and passes. Everybody above the free-throw line except whoever is cutting. And one rule that runs the whole thing:
Your own defender decides your next move.
If he denies you the ball, you back cut. If a teammate dribbles at you and your man is overplaying, you back cut. If your man is sagging, you come to the ball for the handoff. If he turns his head to watch the ball, you're gone. Carril's players didn't memorize plays. They read one defender, their own, and the offense took care of the rest.
What makes it hard to guard is that it turns a defense's effort against it. Pressure the wings and you give up layups. Sag off and five players can shoot. Switch everything and the center seals a guard on his back. The 1996 Princeton team beat the defending champion UCLA with this on a back door layup in the final seconds, and the Sacramento Kings took it to the Western Conference Finals six years later with Vlade Divac and Chris Webber as the passers. You'll still see it in Richmond's offense, in Princeton's, and in every NBA center who runs handoffs from the elbow.
The offense has three phases the coaches who teach it all use: Chin, Point, and Low. I've grouped the twelve plays that way, with the rule first and three specials at the end.
The rule that runs everything
1. Dribble-At Back Cut: the pressure release
This is the first thing to teach, because every phase falls back on it. A guard is denied the reversal pass. The wing with the ball doesn't wait; he dribbles straight at the guard's defender. Now the guard reads. Overplayed, he back cuts. Sagging, he comes for the handoff.
The details the Canadian national team coaches are strict about, and I've adopted all of them: the wing aims his dribble at the defender's baseline hip, not his chest; the guard holds still until that first dribble has hit the floor, then goes; and the pass is a bounce pass that arrives behind the defender where he can't reach back for it, which Lisa Thomaidis's playbook sums up as "low and late." If the guard back cuts from the top and doesn't get the ball, he fills back out on the ball side, never the weak side. The play below shows the back cut covered by a post defender stepping up, then the second dribble-at turning into a handoff, with the post sealing the helper who stepped up.
Chin phase: the two-guard front
Chin runs whenever the post is already high. Two guards in the slots, two wings, the center at the elbow. The ball goes guard to guard, then to the wing, and the first passer gets a back screen from the center.
2. Chin: the back screen and the drift
The cue is the ball leaving the second guard's hands. That's when the center steps up and back screens the first passer, who cuts off the back side of the screen to the far side of the rim. Watch where the cutter's defender goes. Nine times out of ten he stays between his man and the ball, which puts him on the wrong side of the screen, and the wing's pass goes over his head to the rim.
If it's covered, the cutter clears to the corner and the center moves across to the ball-side elbow and sets a flare screen, which Princeton coaches call the drift, for the other guard. The center turns to face the baseline when he sets it, which leaves the guard a straight line to the top. The guard reads his man on the drift: under the screen means fade to the top for the shot, over the top means curl to the rim.
3. Chin, Curl the Drift: when they chase the shooter
Once you've hit a couple of threes off the fade, the guard's defender starts chasing over the top of the drift to stay attached. That's the read for the curl. The guard goes to the level of the screen, feels his man going over, and curls to the rim. The pass comes late by design, because the cutter has to clear the screener's hip, so he keeps his hands up the whole way.
After a curl with no pass, the lineage gives three ways out: the wing dribbles out and the team calls "Escape" to reset Chin, the wing passes to the center at the elbow and runs Corner Over, or the center steps out to the top and you're in the open phase, which is play twelve.
4. Strong-Side Chin: the UCLA cut and the handoff
What happens when the first pass goes to the same-side wing instead of guard to guard. With no reversal there's no chin cut, so the passer rubs his man off the center on a UCLA cut toward the block, and the center steps out to the arc to take the pass from the wing. That leaves the wing with the ball and the center at the arc. The wing loops under the center and takes a handoff from him heading toward the middle, and the moment he turns the corner the weak-side guard gets a flare screen. The handoff and the flare have to land together, or the shooter is open before the ball can get to him.
Carril keyed the same cut off a denied guard-to-guard pass. The play below shows the defender jumping over the top of the UCLA cut, the handoff, and the help defender leaving the flare shooter.
Point phase: the ball at the elbow
Point is a one-guard front with the center holding the ball at the elbow. The passer who entered it has three routes, and the names are exactly what they sound like: Away, Over, and Under. First, though, you have to get it there.
5. Point Entry: the wave and the brush
When the defense denies the guard-to-guard pass, the ball handler waves the denied guard through. The guard cuts through the elbow, brushes the center's defender on the way to the corner, and the center flashes up to the elbow behind him. The handler dribbles to the top and enters.
The counter is the one everybody forgets. If the center's defender jumps above the elbow to deny the entry, the center back cuts for the lob. The Canadian playbook says the post must "own the elbow," and I'd add the other half: if the defense takes the elbow away, the rim is his.
6. Point Away: the screen that's usually a fake
The most common Point action. The passer enters the center and screens away at the opposite elbow for the weak-side wing. The wing reads his defender: chased over the screen or pressed up, he rejects it and back cuts to the rim. Loose, he curls the screen tight. In my experience the reject is the common one, because a defender guarding a wing on an away screen almost always gets up on him.
The screener second cuts back to the top the instant the wing goes, and when the center passes to him, the center follows his pass and ball screens him in the middle of the floor. The playbook I learned this from treats that screen as bait more often than not: the handler sells it, then drives the other way. The play shows exactly that, with the corner lifting off the baseline for the kick.
7. Point Over: the pin-down into a handoff
The passer cuts over the top of the center and sets a wide pin-down for the strong-side corner, who comes off it and takes a handoff from the center, turning the corner downhill as the center rolls. The corner's defender has to fight a screen and a handoff in three steps. If he overplays the pin-down to beat the handoff, the corner rejects it and back cuts to the center.
There are three versions of Over in the coaching world. This is Hooper University's. The Canadian team runs it as a flex action, and Lee DeForest runs it as a fake screen into a side ball screen. Pick one and teach it well.
8. Point Under: the turn-out and the slip
The passer cuts under the center looking for a handoff, and when there isn't one, he keeps going to the rim for the return pass, then clears to the corner. The corner player lifts to the wing and, after a fake toward the ball, sets a pin-down the lineage calls the turn-out. The cutter turns out to the wing for the three.
This is the Point route to run against a team that switches. A switched pin-down leaves the smaller defender behind the screener, and the screener slips it into the lane for the pass from the elbow. The center sees the slip before the defense does.
Low phase: the post feed and the split
9. Low Post Split: two cutters off the feed
Which phase you live in depends on your center. Carril ran Low when he had a post who could score on the block, and the high-post phases when he didn't. The ball goes to the wing and into the post on the block, and the passer has three choices the moment it arrives. Slide to the corner, Laker cut around the post for a return pass, or cut to the elbow and screen for the player above him. That last one is the split, and it's the one to teach first, because the post sees everything from the block and two players crossing in front of him give the defense two cutters at once.
The reads on the elbow screen: accept and cut to the wing when the defender is loose, reject and go to the rim when he fights over, curl when he trails. And the screener slips to the rim whenever he sees a gap, which is the answer when a defense switches the split.
The specials
10. Center Back Door: the play that beat UCLA
March 14, 1996. Princeton 41, UCLA 41, seven seconds left, and Carril, who had announced his retirement six days earlier, calls "center-forward back door" in the timeout. Steve Goodrich flashes from the block to the elbow and catches from a guard. Gabe Lewullis cuts once, and Charles O'Bannon is ready for it, because the same cut scored at the end of the first half. So Lewullis drifts back out to the arc, O'Bannon relaxes a step toward the ball to watch the pass fake, and Lewullis plants and cuts again behind him. Bounce pass, layup, 2.2 seconds left.
The second cut is the counter to a defender who's ready. Coach it as the center's read: pivot, see the cutter, fake, and throw the bounce pass into his stride the instant the defender's weight goes the wrong way.
11. High Post Turn-Out: Carril's 2-3 high
This is the version Carril ran without a dominant post. Guards in the slots, forwards at the free-throw line extended, the center high at the nail. The point passes to a wing and both guards empty out, cutting through the lane to the low blocks. The wing reverses it to the center, who has popped to the top. Now the two forwards drop down and screen for the guards, and the guards cross each other under the basket, each coming off the far forward's screen to the wing opposite where he started, with the center holding the ball up top.
A forward who overplays the turn-out gives up the back cut. The play shows that, and Carril's own notes add the next action: once a guard catches on the wing, the opposite guard dives back to the block and comes off a stagger set by his wing and the center.
12. Open Phase: Princeton meets five-out
Once the center has stepped out to the top, usually because someone just curled the drift, nobody is in the paint and the floor looks like a 1-2-2. It runs like a dribble-at from the top: the center drives at one wing, who back cuts to the rim and, if the pass isn't there, turns and posts on that block. The baseline player on that side comes up to replace him and takes the pass from the center. Now the center has no ball and a post below him, so he goes across the lane and screens for the far wing. If the defense switches that screen, the center has a guard on his back; he seals and dives.
If you've read my guide to the 5-out motion offense, you'll recognize all of it. This is where the modern hybrids start: Furman's five-out Princeton, the Kings' and Nuggets' handoff games with the center at the top. Same rules, faster.
What the defense will do, and what you do back
A good defense settles on one of four answers after a few possessions, and the plays above have a counter for each.
- They deny the wings and the reversal. That's the dribble-at, and it's a back cut every time. The more they deny, the more layups you get.
- They deny the center at the elbow. The center back cuts for the lob (play five). A defense that takes the elbow away has nobody behind the elbow defender.
- They switch everything. Slip the screen. Point Under's turn-out, the Low split, and the open phase's cross screen all leave a smaller defender on the screener's back.
- They sag and pack the paint. This is the one that beats a Princeton team that can't shoot, and it's the honest weakness. Reverse the ball, take the first open three, and run the drift fades until they come back out.
One thing I'd add from watching teams run it badly: the cuts have to be sprinted. A jogged back cut is a turnover. Every cutter has to go hard enough to score and believe the pass is coming, hands ready, because the center only throws it when the cut is real. Get that habit and most of the offense comes with it.
Teaching it
I'd install it in this order, and I wouldn't move past the first step until the back cut is a reflex:
- The dribble-at. Two-on-two, a denied guard, a wing who dribbles at him. Back cut or handoff. Nothing else exists yet.
- Chin. The reversal, the back screen, the chin cut, then the drift with both reads.
- Point Entry and Point Away. The wave, the center owning the elbow, and the reject-and-back-cut off the away screen.
- Low. Only if you have a post. The feed and the split.
- Over, Under, Strong-Side Chin, the open phase. One at a time, against the defense you're about to play.
For younger teams, the coaches who run it with middle schoolers stop after step one and a simple Chin entry, and I think that's right. Expect the full system to take a couple of seasons before players run it on instinct, and don't be discouraged when the first one is mostly film. Either way, the rule comes first and the sets come after.
Wrapping Up
The Princeton offense is one rule and three phases. Read your own defender, cut when he gives you the rim, and let a center who can pass run the show from the elbow. It made a small Ivy League school a problem for everyone for thirty years, and the ideas are all over the NBA now, just run faster.
