Listening to the Joel Klatt show today, which was a very good listen, and he brought something up. The idea of a super challenge. (I think he could spend more time on the name but I digress) 1 challenge per game where you can challenge any play, any call, any non call, whatever. It wouldn't add much time to the game and the coaches get a chance to have a play like the non-DPI that was called against Barron looked at. All the referees get together, watch the video of the play and discuss. There are a lot of instances where 1 really bad call or missed call can affect the game and this is a pretty simple way to fix it, or at least let the coaches have a chance at arguing it.
