Oh, so it's minutiae after you got the quote wrong?
Well, since you asked, using slavery to define cholarship athletes is certainly hyperbole. You know, exaggeration for effect. So while it's certainly not slavery, consider the scholarship athlete. He can't even do his laundry without wondering whether he'll get suspended for not using official NCAA approved detergent. More hyperbole, but you get the point. Really, unless a kid already has reasonable means (as in, his parents have enough money to send him some now and then), he's effectively a prisoner of the NCAA guidelines. A lot of scholarship athletes don't much apart from their scholarship. I know what it's like to have nothing in your pocket but your meal ticket while several of your friends even have cars and can put gas in them, etc. It was complete BS when a couple SU basketball players were cited for getting a minimum wage job handing out towels at the local YMCA, while the NCAA and the schools make hundreds of millions of dollars. So I think something does need to be done for scholarship athletes in college today. For "fair" is not the same as "equal" and the NCAA apparently doesn't understand that. Nor do they want to.
