Well, there is one reason. Money. Those scholarships are expensive. If each cost $50K and we bring back 20 seniors, that comes to $1 million dollars. Where does that money come from? SU, and all the other schools that play football are all in awful financial shape. Even Clemson is cutting sports.
If it would be tough for the football program to pay for some extra scholarships, what about the fall sports that do not normally generate revenue?
Bottom line, I think maybe we bring a couple of players back for football only. If we are lucky. If we do, it will be because donors or the JB Foundation ponied up the money.
