Princeton:
"The short answer is Princeton effectively eliminates mid-range jumpers. If you play it your team will usually either shoot a 3 or go inside.
In very basic terms the Princeton system is four guys stood at the three point line, with your center stood just outside of the paint. The ball is passed between the four outside players and this forces the defence to constantly shift. The tempo is very slow and the team has to be patient and waits until the defense makes a mistake. The defensive mistake will usually lead to a defender having to come and help, leaving an offensive player open, either for a 3 point shot or an open lane to drive to the hoop.
In real life basketball Princeton is a tough system to defend - but it's also a very hard offence to execute. You need all players to have good passing and driving skills and you need good shooters. The center also plays a pivotal role, he needs to be able to fight for his posisiton inside, then pass out of a double team.
I guess it's the same in buzzerbeater - you need your 1-4 players with excellent JR, passing and driving, and an inside guy who can drive and pass.
The only difference is in buzzerbeater there's no stat for "help defence", and really Princeton is used to exploit teams that are poor help defenders and poor at rotation.
So the positives of using it in BB - you'll get a higher FG%, usually more 3 pointers and because it's a slow system you can play a fast defence like full court press.
Negatives - i assume you'll see a lot of turnovers and shot clock violations. Teams with good OD will be hard to beat."
