Adidas probably recoups most, if not all of that 90k before the kid ever leaves college. I mean if Adidas is funneling talent to Adidas schools, that probably goes a long way in securing future contracts/merchandising with those schools. Plus, since they are sending higher talent to those schools it stands to reason that that schools would see an uptick in successful sports, which would lead to a larger fan base and more tee-shirts sold.
So Adidas most likely got all of that investment back whether or not the kid makes it to the association. And if he does, then I'm sure Adidas probably got the kid or the kids handler to agree to future considerations should they someday be in the market for a shoe contract.
Seems like a no brainer, I dunno
