I feel they should be able to challenge a judgement call. It's just as important as any other call, and a game's outcome can hinge on it. Like someone else on here said, you can always fall back on "inconclusive evidence". Watching the called force out on Arizona's Fitzgerald, it wasn't even CLOSE to the obvious force out on Franks. I mean, if instant replay is being used, why NOT use it in these kinds of cases? Like Trippster said, the refs have a split second to make the call, and in this case is was obviously the wrong call. Whats the damage in allowing them to look at the replay and see if they did make the right or wrong call? If it ends up being so obviouly wrong, then they can make it right. And if it's still ruled as the right call being made, then they at least looked at it. And like in the Franks case, let us challenge it and take the chance at losing a time out if ruled wrong.
