it not nt the point. those type of blocks can ruin a guys caree. you understand how bad that could of hurt he guys knee. its the same thing for lineman also. you can just go to block some one and take there knees out liek that. the nfl is only trying to procect its players. vice versa you can drill the qb down to the ground once he released the ball. i know its a gray area but still the nfl has to procect its assets.
