I disagree that driving is very important. It helps but driving is used more in other offenses like look inside and push the ball. I think Princeton is a passing based offense. Also your big men need to be able to shoot and pass to get the most out of the offense.
I actually think Princeton is a good offense for teams with so so guards but great, well rounded forwards.
Actually, that makes a lot of sense, as RnG tends to take the most out of your guards and LI tends to take the ball to your post players all the time, there should be some tactic that is forwards-oriented.
And those skills schemes depend on your team structure, passing is the #1 skill for Princeton, that's sure. If you lack good offensive centers and PFs, your guards and forwards infiltration, JS and JR will take a big part in your scoring. But you can still play Princeton if your perimeter players aren't good shooters but are good passers and you've got a superstar center.
