You 've never seen it because, its done below the waist with the hands up so you can swim your arm over the over man's shoulder.
Post play is not for the meek. The move works very well. I guessing you have never played past biddy ball from your naivety.
Post play is somewhat dirty and one if always trying to get an advantage. Here is another that goes on all the time. You box out beside the guy keep your hands high. This is critical so it looks clean. The refs will call anything that looks like a foul, there doesn't have to be contact. You then push down on the opposing players shoulders holding from jumping up, with your elbows. The refs never catch it because they are looking for pushing at the waist level. A lot of the pushing in the post is done with the thighs and the refs don't always catch it. Give your best choir boy look, murder them below the waist and get those boards.
here is another, I 've seen Larry do this one. You lean heavy on one side wait until the man shifts his weight into you, then step over to the other side to get inside of him whist he is off balance. The other man will be lucky not to fall if this is done right.
If you took a swing at me in the game, you would get a foul. I would not. They always catch the retailiation but rarely the instigator.
That being I would love to play a game with you and let you take a swing at me. Perhaps we could meet somewhere, where I am from talk is not cheap my man, one does not speak of throwing punches without being ready to back them up. Your size matters not to me, I am willing to go against you.
