Game day is devoted to the game. If they travel out of town to play, the entire weekend is devoted to the sport. The entire student body benefits from the sport. When I was a graduate student at the University of Florida in the early 1980s, for example, proceeds from Gator games literally bankrolled summer school. The money was a godsend because budgets were tight.
Football is a plantation.
Football is big business. If nothing is done, the system will continue to corrupt players and their universities. Please do not tell me that these players are students before they are athletes. But I know that it can be done. Most universities have competent business colleges.
