I just want them to repeal the 1978 bump and run rule. A defender should be allowed to hit and rough up a receiver as much as he wants until the ball is in the air. I can't stand the dumb rule that says it can only be within the first 5 yards of the line de scrimmage. The made that rule in 1978 to handicap the game in favor of the offense, and I've never liked that. The game was better before they made that rule. I don't think games with a lot of scoring are better. I don't think the rules should help the offense. If a receiver wants to be able to get open, he should have to earn it. No more of that annoying "illegal contact" penalty.
Also, fix the PI challenge. If the red flag is thrown, it should not be that complicated. The ref should just watch the video and see if there's PI or not, and then rule accordingly. They tried to make it too complicated, saying a reversal could only happen if it's blatant. The heck with that. If the defender is there before the ball gets there, it's PI. If he arrives at the same time or after, it's not PI. It's that simple. Rule accordingly.
