I read support from two other Oregon players....that doesn't constitute "many."  The role of a strength/conditioning coach is to develop individual regimes for players and supervise their progress, not to push them beyond their limits and send them to the hospital.  If you think 18-24 year old scholarship football players are going to "wimp out" and say "hey Coach, I just can't do any more", you've never been around football.  The Coach is, theoretically, trained to have the judgment and knowledge to know when "enough is enough."
