You beat me to it. I don't understand this "if the whistle blows" crap. If the call is wrong.....Change it. Sure as HELL don't wait 5 minutes to decide that you can't even review the play.
GET RID OF REPLAY.....It's NOT working!
plays should never be blown dead period because teams are always getting scores taken away. Imagine this scenero- a running back fumbles the ball and the defense runs it in for a score, but the ref blew the play dead saying that his knee was down, but review show that his knee was not close to being down; therefore the play is not reviewable and you frack the other team out of seven points
