Do away with the pass interference penalty. I don't know why it's needed, anyway.

I believe it will cause coaches to hang onto the flags until late in the game, you only get two challenges a game, what could be interesting at the end of the game when they throw the Hail Mary.

can we get a challenge and replay on the cheerleaders twerking?

It’s a pretty important rule. There would never be another deep pass caught, and catches as a whole would plummet.

It needs work and needs to be called properly, but it’s a necessary rule.

rules don't work unless there's continuity in enforcing them. after last year and the blatant missed calls....i'm one of the conspiracy theorists that think it's all decided in Vegas before the game

They could at least do away for the rule for an exhibition game and see what would happen. They need to do something to speed up the game. A one hour game on TV often lasts four hours. With this newest challenge games will last even longer.

Nope. Defensive backs would just hang on receivers starting at the line of scrimmage.
