Now that's just silly.
If I found out that one or two years from now, I'd likely be getting a fat check for $20 million, I'd still be exceptionally happy to take $50K now. It seems absurd to me that you'd think that future money would prevent him from wanting money right now.
The only way I'd turn down money now is if I knew that taking that money now would prevent me from making $20 million a year or two down the road. But that isn't the way it works now is it? Not if you're a lottery pick. The NBA isn't going to not draft you just because you took a check or a heavy handshake while in college. That shit is irrelevant to them. The only situation where it's possibly had an impact is Silvio DeSousa, but he's always been a marginal future NBA prospect. It would have no impact on a guy like Zion, now would it? A, the chances of getting caught are slim, and B, even if he gets caught and has to sit out his only year in college, he knows he's still getting drafted early.
Anyway, the fact that he was shopping in the first place, makes your whole argument null. Obviously, he wanted to get paid anyway. If somebody's shopping, they're shopping. They aren't going home empty-handed.
