Here's some rules to compare

[RefsNCoaches]

The youth league that I work with has similar rules. Some differences being only giving 4 full timeouts for the game with 1 additional granted for OT.

For 3/4 grade, they must play M2M and they have an isolation rule in place if the better player(s) take all the shots. If the same player takes a shot on three consecutive offensive trips trips the 3rd shot is whistled dead and a warning is given. If the same player takes a 4th shot we whistle a T and the other team gets the two FTs and the ball. (really, I think it would be more deterrent if given 2 points and the ball).

Now within that, offensive rebounds and immediate put-backs do not fall under this rule..it's something more assessed as they set up in their half court sets. The idea is that they get all players involved with ball movement.

At 5/6th, 7/8th grade it's wide open basketball with the exception of no press until the final 2 minutes of the game and last minute of 2 minute OT period. Also, no press if up by 10 or more.

Our HS league (9th-11th) is straight NFHS rules with the only exception being 20 point - no press rule.
