Not sure if mentioned, but with respect to the apparel companies signing players - that should also play into transfers.
Let's say we sign Bobby Bobberson, and he signs a Spyre deal for $100,000 and a Nike deal for $50,000. Well after his sophomore year he decides to transfer. He loses his Spyre deal but as long as he transfers to another Nike school he will keep his Nike contract.
Let's say we want a transfer from Bama real bad and it's between the Vols and Texas A&M. Well, he's already got a Nike deal, so we might have a slight leg up because A&M is Adidas and he'd have to drop his Nike deal (and maybe pay out a penalty or whatever else they write into it) to go to A&M.
Note: Jordan brand is owned by Nike so it doesn't affect Florida that much. All the same.
This might really affect the Pac12 (adidas, nike, and under armour schools) and I think I'll be bigger for basketball than football.
