That's precisely the problem. Let's say the NCAA were dismantled and it became a free market for athletes, the wealthy schools will thrive and then other 90% will suffer big time.
These athletes get so much more than even just the high price scholarship - attire, access to trainers, first class training facilities, exposure to pro scouts, priceless experiences, a chance at leaving some terrible home situations, etc.
If this or similar efforts pass - which it is just a matter of time - I can guarantee you that ticket prices are going to spiral out of control and most of us normal fans will be priced out. Somebody has to pay the ever increasing bill this will create.
