Listen, children. You are arguing pointless BS right now. As a former D-2 football player, maybe I can shed a bit of light on this subject (I was well acquainted with a few UM players under Coach Carr).
Coach Carr/Gittelson's system involved virtually no free weights. It was designed to keep players from potential injuries that arise from strenuous free weight exercises. Michigan was taking top athletes and putting them through body builder workouts.
Coach Rod/Barwis' workouts involve intense free weight exercises that are potentially (if done incorrectly) more hazardous but also more beneficial to stabilizer muscles. This type of workout TRANSLATES BETTER TO THE FOOTBALL FIELD.
Between how I trained in high school (Gittelson-like workouts) and how I trained in college (Barwis-like workouts), there is no comparison. I was more cut, more flexible, faster and shiftier in college. Yes, I was older, however the college workouts markedly improved my overall game.
To conclude this long post, Coach Carr's program was antiquated, not a "country club." It was not the type of program a football team should run if it wants to maximize potential. The players that did not like the new workouts (Boren comes to mind) were probably, in fact, "lazy" due to the more intense workouts, however the change in atmosphere is most likely what upset them most.
