Ah, makes sense I see what you're saying. You got a good point, but theoretically some of these kids might take advantage of the opportunity to get the paid for degree in something useful. I understand that's usually not the reality though.
These are more just ways for the schools to make money and use inner city kids to do it. The kids playing college sports who have no NFL/NBA potential or academic potential are probably better off just working instead of going to uni.
