You're Commissioner For A Day In The NFL....

In pretty much every sport the first thing I would do is change the replay system. First make it collaborative between the on field ref and the video ref. Second they both look at the play once in regular speed, once in slow motion. If they both agree that the call wasn't clearly wrong, get on with the game. If one or both has doubts then you can look at different angles, etc. And finally a limit on how long these things take. If two refs can't find something wrong in 2 abd a half minutes, no great injustice has taken place.
