There sure is some over reaction here.
Defensively, there were too many injuries. Teams have been studying injuries for over 50 years. Why does an old player like Pickett not get injured yet many of the younger ones are always hurt?
Don't think that we are the only ones wondering.
I'm sure Pepper Burruss, Dr. Pat McKenzie, and the rest of the training staff have meetings on the very subject.
I'm sure they go to NFL seminars and learn what other teams know and share their knowledge with them.
I'm sure decades of injury statistics and common factors have been researched.
I'm sure that all that can be done under the current CBA is being done to prevent/limit injuries.
It is why the shotgun approach to the draft is successful. No one can predict where the injuries will occur but there is always one position where they seem concentrated.
