I'm by no means an expert on football, but it seems like a wildly dangerous play to essentially treat your quarterback like the ball. Sure, it can work; but if he gets injured, then what?
Brady did QB sneaks all the time, and it worked quite well for the Pats. Are QBs more likely to be injured on sneaks? It seems pass plays are the worst for QBs, with potential sacks and hurt knees and ankles trying to get away from the rushers.
I agree with this in the case of major concussions, but we see a lot of serious injuries come from large guys on the line falling on the legs and ankles of other guys, and generally just getting your legs rolled up on. That being said, this play doesn't seem to be any more dangerous than any other play where there's a big scrum.
They have the perfect personnel to execute this play. Highly strong quarterback and an elite O-Line. If other teams could do this, they would. What’s stopping them from putting an AJ Dillon under center when they attempt these plays.
