If this gets overturned, there will be one untimed down, correct? OK, all things considered, going in down 13-7 at the half wouldn't be a disaster. Super Bowl halftimes are much longer than normal game halftimes, so this play doesnt half to linger too badly...
Looks to me like his helmet is down while the ball hasnt crossed the plane yet... should be overturned.
EDIT: Wow, I don't think the ball is near the goalline when his helmet hits the ground. How do you let him rumble 100 yards?? Looks like Fitz could have tackled him low, instead of going for the strip... what a turn.
