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 said he borrowed it 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:
The man guarding you tells you where to go.
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 cut with four seconds left, 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: dribble at the baseline side of the defender, the guard doesn't move until the ball has bounced once at him, and the pass is a bounce pass thrown low and late behind the defender's hip. A back cut from the top comes back out on the ball 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. The defender almost always goes ball side of a back screen, so the wing throws over the top.
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 screen is angled with the center's back to the top of the key. 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. The wing then circles under and comes back for a handoff with the center, and as he turns into the middle, a flare screen goes up on the weak side.
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 puts it simply: the post must own the elbow, and if he can't, he owns the rim.
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, which is what happens most of the time on film. Loose, he curls the screen tight.
The screener second cuts back to the top the instant the wing goes, and when the center hits him, the center follows into a middle ball screen. The playbook I learned this from says the handler should look at that screen and reject it a good percentage of the time. 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
Carril's rule for picking the phase: a strong big man means run Low. 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, 3.9 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 guard passes to the wing, both guards cut inside to just below the blocks, the center steps out to the top and takes the pass, and both forwards down screen for the guards, who criss-cross under the rim and turn out to the wings beside the center.
A forward who overplays the turn-out gives up the back cut. The play shows that, and Carril's own notes add the continuation: when the turn-out is caught, the other guard cuts back low for a staggered double screen from the wing and the center.
12. Open Phase: Princeton meets five-out
When the center has stepped out to the top, usually after someone curled the drift, the offense is in a 1-2-2 with the paint empty. The center dribbles at a wing, the wing back cuts, and the corner lifts off the baseline for the pass. The back cutter stops and posts. After the pass, the center screens across for the weak-side wing, and if the defense switches it, the center seals the guard 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. Carril's players cut to score every time and expected the pass every time, and that habit is most of the offense.
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. Carril's assistants said the full system took players two or three years to really own. Richmond's guards say it took a season of 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.
