Or somebody starts a football minor league. (this must be my fifth post suggesting this)
There should be a way for athletes with NFL dreams, but no academic goals, to prepare without going through the college path. Players would be free agents, sign a one year contract and be paid according to the market for their ability. And the pay would have to exceed the under the table money offered by the schools.
College football would continue with less headaches from the portal and early opt outs. NIL money would decrease since many top prospects would be in the minors.
Recruiting would be different since athletes would have options of college or minors.
Certainly not a perfect solution, but it should be an improvement.
