I am a junior high coach, and all the way through our entier program, hs/jv and junior high, we run something very similar to what brey said before me.
We actually start in a 1-4 high set, just to give a different look. However, when the ball goes to the wing, one of the players at the elbows is designated as the low post player and he goes to ball side short corner. The other player on the elbow goes to ball side high post.
Whenever the ball goes to the man in the short corner, a couple of things happen. 1, the wing drops into the ball side corner. 2, the high post man roles down the lane. 3, the opposite wing drops to the baseline on the back side, for a pass along the baseline. 4, the player at the point then floats to the opposite wing. You want this player to be a good three point shooter because he will get alot of good looks.
We have found that the short corner is the weakest spot against a 2-3 zone.
