So, your knees don't play any part in deadlifts, or squats or the 1000 other exercises that require bending of the leg? No, you're totally right during conditioning the knee just ceases to function, it only turns on for season games or random injuries.

ACL tears like the one Navarro Bowman suffered two years ago, where you on on the field in the middle of a game and a lineman falls on your leg are a fluke. ACL tears that happen in training camp aren't bad luck or flukes, it's indication the players are being pushed too hard or not enough attention is being paid to what they physically can handle. I don't think Breshad is a bust, I don't think it's even his fault at all. I think he has a lot expected out of him and probably both himself and the staff were once again pushing to get him ready for the season. Weight lifting and such strains and tears muscle, it's how you build muscle, by straining it and softly tearing it and allowing it to rebuild. When you push too hard, without care of your players well-being, muscles tear too far and you end up with what you have here, season ending injuries in training camp, again. There's never been a single case of "oh I was just walking down the street and my ACL randomly tore, what a bad luck, but happens all the time you see people laying there on the sidewalk with torn ACL's, them things are just so fragile."
