I hate answering questions with questions, but...
Does BYU suffer more injuries statistically, than other football programs?
Does the limited contact in fall camp prevent weaning out injury prone players that catches up during the season?
Then, sorry to sully, but have to...is our current Offensive scheme promote higher rate of injuries among qb''s? I thin PK we know the answer to this question. And that is at least half of the answer to your question.
