That's why you're not a referee :)
Personally, I think the refs were going to review the play, they needed to blow the whistle BEFORE the snap.
It seems that they did not have time to do that... Look at how quickly they ran, spotted the ball, etc. Imagine if you are the referee or umpire and are just getting buzzed a half second before the play is going off...
By the time that you are blowing your whistle the ball is being snapped. However, the actual buzzing took place before the snap, which is what the rule calls for.
That's why I don't agree with the rule that the officials themselves decide what to review in the final two minutes. They screwed the Lions twice on Thanksgiving, first by NOT reviewing a play that should have been a touchdown and then reviewing and incorrectly reversing a play where the Lions completed a pass for a first down.
The coaches should be allowed to challenge a call at ANY time during the game as long as they have challenges to use and this should include the final two minutes.
Bottom line - the officials screwed up by not stopping the play before the snap. Once it is snapped, they should have no recourse, just as they always tell the coaches regarding inadvertant whistles. A dangerous precedent has now been set to review plays even after the next play was run.
As to whether I'd be a good ref, I defer to former Oiler coach Bum Phillips when asked once why he didn't become an official he said, "because I cain't. I'm overqualified. My mamma sent me to school."
