Why oh why doesn't the NFL jump on the bandwagon and go to the NCAA model for IR? After watching a few games this weekend got me to thinking (a dangerous thing). Why have the R go "under the hood" for God knows how long to make a determination. By the time he gets mic'd up and enters the "voting booth", an official in a replay booth could have probably already determined the outcome. Then you've got the stupid rule about losing a challenge. I saw one challenge that clearly should have been overturned confirmed, and because of that, later in the game, an interception that replays CLEARLY showed the db's second foot well out of bounds could not be challenged. If the NCAA model was used it would have been overturned, but because the coach had no challenges left, the play stood while all saw it was not an interception. If you are going to use IR, why not use it to get the calls right, not just the ones while the coaches still have valid challenges left, or in the last two minutes?
