I think the conversation veered way off topic. What was originally described was a receiver that is going for the ball and a defender making a big hit on him. Not a helmet to helmet hit but a big time crushing hit. On any pass play, it is the defenders responsibility to not let a receiver make the catch. You either make a play on the ball or you make a play on the receiver if you cant get to the ball. If you make it on the receiver, you have to hit him hard enough that he does not make the catch. Again it is tackle football. This is not a cheap shot nor is it dirty. In fact if anyone wants to complain about a coach, they may want to complain about the offensive coach who should be coaching his quarterback on what passes shouldn't be thrown. I have seen too many games where a middle linebacker is playing zone and the coach will call a pass where the receiver is supposed to make the catch as he comes across the middle. Yes the receiver is going to get blown up. No it is not the defense's fault. Now as far as the cheap shots away from the play, going for the head or going for a players knees.. I think those should be called without question.
