Gronk is as close to unstopable as there is in the NFL. You can't give up on guys like that (if you do it will come back to haunt you).
The ACL is, unfortunatly, an injury that can happen to any guy on any play and the bigger and stronger you are the more likely it is to happen because the little DBs go low.
He needs to learn how to hurdle over safeties when they go for his legs.
