I think that the Net's are not running the old Princeton offense as well as they use to 3-4 years back. The Princeton offense is all about back picks & rolls, guys spotting up for the 15-20 foot jumper. They use to have guys like Kittles & Lucious Harris that were perfect for this. Kenyon Martin & Aaron Williams were anchors setting strong picks and rolls with J-Kidd.
Nowadays they seem to have so much indavidual talent with R.J. & Vince. They tend to pass the ball and watch an isolation. You do not see anymore of that beautiful movement WITHOUT the ball the Nets use to have.
The Princeton offense needs players to be in constant motions looking for the ball, but it seems that you're right about too much individual talent. There seems to be a lot of one on one with RJ and Carter, not so much in a selfish way, they'll still dish the ball, but there isn't as much motions without the ball by the Nets.
They run seven or eight basic sets, and within those sets, there are about 12-20 variations. For example, their “Chin” series is like the old UCLA-John Wooden offense, but within it, they’ll call “chin 15” (basically a guard-to-guard pass that goes into a high screen/roll), “chin-LA” (basically Jason dives to the opposite block, and posts up), “chin-LA2” (Vince fakes the same UCLA cut, them comes off a weakside pin), “chin flash,” “chin special,” “chin swing,” and about 10 more based on that single format. The other basic sets are “Fist” (pick-and-roll sets, mostly – example: Marcus ran “fist 1-5” with Mikki Moore about a half-dozen times in that fourth quarter at Phoenix), “Elbow” (mostly wing action for Vince or Richard), “Forwards Out” (mostly dribble-handoffs, designed to make the ball change sides of the floor), “Rub” (these are motion sets, based on the old flex offense), “Zipper” and “Same Side.” Again, within those larger groups there are more than a dozen variants, which means the playbook consists of probably 150 individual plays, and he’ll use about 50 of them on a particular night -- basically calling a lot of motion stuff (forwards out, rub) early in the game, and screen/roll stuff late.
