I don't know anything about how princeton works, so I can't say anything about that...
Princeton makes your team shoot fewer mid-range shots, and focus on inside and outside (long range) shots. So your team would shoot more inside shots and 3 pointers and less 2 point jumpshots. Princeton is also played at a decreased pace from the base offense, so it is slower paced than motion (normal paced), which is slower than run and gun (high pace).
Coach CC, for your offense, I agree with Burninator. Use either Run and Gun or Motion if you have good outside shooters and are playing against a team using 2-3.
