If you think instant replay is a complete disaster, what about the football selection committee? We got rid of the BCS and in the process we got rid of the computers which threw out all bias and voted without prejudice or passion. Something is wrong and it's not getting any better in this sport on a year to year basis.
If I could change ONE thing in this game today, it would be to remove that bullshit targeting penalty. It's football, the goal is to HIT other people. It's our modern equivalent of gladiatorial combat in an arena. Stop treating it like a damn knitting circle.
