These guys are professionals or suppose to be anyway! They have been playing long enough to know what they can get by with and what they can’t! What really gets me is that an official could call holding on every play no matter what team is playing! Look at the stats on the offensive line on any team Tom Brady has played on and it’s very seldom that they get flagged for holding! Now could it be because he is an high profile player that brings people to the games and the league would loose money if he gets hurt?? It’s not just him but others also! Another thing that’s bothered me for several years is when the Cowboys played the Eagles at Philadelphia four or five years ago and Philadelphia played the entire game without any penalties called on them and there were a few occasions that the announcers even pointed out holding plays that was never called! The way I see it is if the foul is an direct result that kept a player from making a play then call it but if not let it go! Not everybody likes America’s team and those that don’t love to see them loose!
