I don’t know the answer.
I remember two seasons ago, the only significant injury the Bills suffered was Tre White’s ACL. The Bills training staff was being credited with keeping the players healthy.
Now, compare that to the past two seasons. Does the training staff deserve criticism for all the injuries we have suffered through?
I don’t know. Seems to me that training staff’s across the league are probably pretty comparable and injuries are just a good luck/bad luck sort of thing for the most part.
