I don't think it's as dismal as you make it look. My brother just accepted a football scholarship at a highly academically rated BCS school. I think there are 66 BCS schools and each one gives out about 20-24 scholarships each year. It's a huge opportunity to get a free education, play a sport he loves and make lifelong relationships with his teammates. A football locker room at the highest levels is about as exclusive a club as there is. I don't know how much tuition is or the other things the scholarship includes, but I wouldn't be surprised if it approaches $200k.
He can be a fool, get beat up and leave without a degree or he can take advantage of an opportunity many people only dream of. The coaches aren't telling him what classes to take. He can take whatever he wants. He can choose a useless program, a great program or anything in between. He can choose to meet the minimum requirements to stay on the team and keep his scholarship or he can choose to excel academically.
On the field, he can choose to hide a concussion or take some time off. He won't lose his scholarship over it. Most players feel pressure to play through injuries, and although it can come from peers and coaches, they often place most of it upon themselves. They are incredibly competitive and don't want to be sidelined for anything.
My point is all the choices are his to make. The same applies to other players. There are few victims in this who aren't victims of their own decisions. If a kid washes out of some dumbass cake walk program for kids who don't give a shit about school, sustains injuries in a sport he would play with or without a scholarship and has zero career prospects is that the fault of the system? I don't think so.
There are ways to twist it around to make it look like a scam, and it's true there are plenty of things wrong with college football, specifically the BCS. It's a feeder system for the NFL, a bunch of people make piles of money and the kids don't make anything. It may be all of those things, but it is also an opportunity for the lucky recipient of a football scholarship to change his life, either for good or bad.
