this rule drives me nuts. I think, and stress think, it was in the Giants game and a RB was being held up, and Titans player wound up and with a full right uppercut tried to jar the ball lose. He got all arm, no ball...and the ref even came in and you could see he was warning him. To me, a punch is a punch...it is either legal or its not. Like you say, getting to take a free swipe at a guys junk with the defense of "just trying to knock the ball lose" is BS. Watt misses a lot on his "Peanut Punches" btw
