In College, there are 2 many plays in the game where the WR totally blows away the CB and you see many more uncontested deep balls.
When you watch 2 bad teams battle it out in college or 2 really talented teams, one side defense and other side offense... you watch CB's that get beat just haul people on the ground...
At the NFL no matter the teams, there are not nearly as many WR blow out plays where the defender is not even close.
So, you want to see Josh Allen throw the ball 50 yards down the field, Diggs has his man beat and instead of contesting more for the ball he just stops Diggs from getting by him by all means necessary? that is not right either... Let's be practical here... There has to be different levels of PI calls and the Ref will still mess up what call to make... 15 yards or spot foul? then after games we will be saying... "refs should have called it spot foul and not 15 yards"
You don't change the call that is broken... NO. You change the morons out there making the call! PERIOD! I see college refs that are way better than what we have now. IF I worked at McDonalds for example... and I screwed up as often as these refs do in a 4-hour period, would I have a job?
