This. It might have avoided the sack but wouldn't have been close to a first. You can't predict when or if you will be injured on a given play. As far as the game, taking a sack and completion to Graham were equal. Carr sees the hit from the front coming and clenches up to protect the ball. I don't think he ever saw the guy who leapt and committed a roughing violation. It's really a non issue. Main issue is OMG BLOCK SOMEONE.
