The rule is so utterly stupid I'm having difficulty fathoming the ineptitude of the idiot who came up with it. Having a player sit out because his helmet came off is just ridiculous, especially if it was caused by an aggressive player using his hands against an opponent's face mask. Stopping play when a helmet comes off is the only understandable part of this bile they call a "rule." But the possible 10-second runoff could ruin a game; also, what happens if a quarterback's helmet gets knocked off on the second to last play of a game? What if it happens to a guy like Matt Barkley right on the second to last play of a game down by four points? He's going to have sit out and pass the reins to the back up simply because his helmet flopped off his surfboard hair?Exactly. Besides it's not like having a player leave the game is going to prevent them getting hurt on the previous play when their helmet came off. Can't wait until some players are trying to pop each others' helmets off in a pile.When was the last time someone had serious injury after his helmet came off?
They've put in a stipulation that if a player takes off an opponent's helmet through a foul (like a facemask) he won't have to sit out, but they're not allowed to use instant replay to judge penalties. So what if a couple of people sack the quarterback and then, in the scuffle, remove his helmet? If a penalty isn't called, the quarterback has to sit out.
So much for good intentions. I know they believe they've got the player's best interests at heart, but this rule is pointless. The only part I like about it is stopping play if a helmet comes off mid-play.
