The gaps between the haves/have nots at QB would be completely insurmountable at that point.
Right now you can still compete and at least make the playoffs with an average QB. If everything was no huddle, you'd have 6-8 teams that would just fist-**** the rest of the league.
There'd be one way and one way to win only. It would become arcade football.
Nah, I'd probably end up watching fewer and fewer NFL games at that point and turn my attention to college football, where you can still win using several different styles.
If you can't draw a crowd, draw dicks on the wall.
