I agree with you completely. The intensity for players and by the D1 coaches borders on the brutal level. This is especially true in the big name conferences ( ACC, SEC, Big East, Big 10, Big 12, Pac 10 etc.
ACC also adds fuel to the fire with their crazy Thursday/Sunday conference game schedule.
Away travel teams often must leave on Wed night and don't return till late Sun night or early Mon morning missing a lot a class time.
