[Ref in PA]

First, you have to see the play.

For me to consider the contact a foul, the path of A5 would have to be altered because of the hand on the hip (could be the speed or direction that gets altered). If I deem the contact was a foul, I then have to decide where the foul occurred. If on the dribble, I would call before the shot, otherwise, we shoot 1 after the made basket. I am there to ref the game, not the stupidity of the defense. Even though the result of the contact by B5 was not successful (A5 still scoring) the foul still occurred.

Now, in the play you described, it didn't sound much like a foul. It would have to be pretty a obvious hold/push for me to blow the whistle - but if it did happen, I would blow the whistle. Would you withhold the whistle for a smack on the wrist and A5 still scoring? No advantage/disadvantage there.
