A1 on offense goes through the lane within the confines of the offensive scheme. B1 is on his hip the whole way, a couple of bumps here and there no advantage. When A1 returns to the wing, B1 is still there on his hip. A1 now gives B1 an elbow to the head to gain some space. I blow the whistle, give the intentional foul signal, call my partner over and ask him to escort A1 to the bench. At the table I have intentional flagrant foul, two shot, the ball and A1 is ejected. In Ct an ejected player must sit for the next game. The Coach of Team A, of course, went nuts, when I explained the scenario to him he rolled his eyes went to the bench and made his player leave the gym.

I agree with you all, If you feel its flagrant, send him home. If not, PC and move on.
