The problem that you encounter when the issue of paying players arises is that the majority of schools in DI, or whatever they are calling it these days, would struggle to afford it. OSU, Bama, Texas, Michigan, USC, and the other big players in the game would have no problem with it but what about the Western Kentuckys and Kents of the world? They and most of the rest of "mid-majors" finish in the red every year. Very few teams make money off football. Lets say you paid 100 players $300 a month for 9 months, that equals out to $270K and thats just football
On the issue of what they sold, did you ever get rid of a trophy or an award from when you were younger? Those guys played and earned those items and in theory can do whatever they want with them (except in the eyes of the NCAA, or course).
