You something about fast break attack from 2-3 zone. so you dont think run and gun would help that since it basically a fast break attack of offense?
I watched a few 2-3 zone games it seems to be based on stamina or game shape and bench defense. its always th same type of collapse every game, every team. I played a game of it and its he same as your game in collapse.. I think team motivation, Like crunch time would help 2-3 zone be played better.
