Rebounding

[Forksref]

JV game this week: Player B has good block out position on rebounding and is moving the A player back during the shot. The A player did not jump. Coach of B says, "That HAS to be over the back." On the transition the other way I tell the coach, "Not when he's backing up. Who initiated contact?"

I know it's semantics, but "over the back" is legal to me, "ON the back is a foul." That applies to this situation: Earlier in the game we had a very tall player from the A team go up and get a rebound over the shorter B player who has position in front of A. No contact. Of course the B coach wanted a foul. I wish they would realize that it IS possible for a player from behind to get a rebound cleanly AND it is possible for the inside player to be the one to initiate the contact. I like the verticality principle, but most coaches and fans have no clue.
