Foul on jump ball to start game

[OHBBREF]

What would you do if it was a throw in and before the ball is at the disposal there is jostling for position or some tugging going on?
I make sure that it is addressed openly so everyone in the gym knows we see it, before we have to call a foul of some sort here with a dead ball.

We specifically cover these types of things in pre-game so we are all on the same page, IMO if you step in and stop this action before hand, especially on the jump, it will go along way toward a better evening, than having to give a non-administrative T before we even have the toss.

The impression given right away about being in control of things should make for a much better game.
