Maybe not the entire sports....but watch how many football programs fold tents.
1. The UT Martin, UTC, Toledo, South Alabama, La Lafeyette,, Troy, etc... of the world will start to fold.
2. The fanbase of rest of schools that are not SEC and Big10 will get squeezed. How long do you think fans of MAC, Pac10, AAC, etc... will be cool with watching their better players get NIL away after they took them out of HS and developed them?
3. Then the lower P5 schools....Vandy, possibly Ky, NC St, Indiana, Mizzou, etc... you think the fans will be invigorated to watch their better players get Nil to bigger schools.
Bama, UGA, FSU, Auburn, etc...are filling spots they have with other teams they compete with from their better players today. I mean it's always been sort of not a great job to get a ton of 5/4* players at Bama, UGA, Ohio State,, etc..and beat conference foes. Now you're doing that and taking their better players and beating them. It's essentially a glorified AAU/travel ball team. The big deal will be getting old sooner or later.
I mean if Saban is such a great coach....why did he do 1 year in NFL....and was not very good and bolt back to NCAA/Bama? If he was the 2nd coming of Lombardi......why was he a nothing burger in 1 year in NFL?
