I agree with this. Its actually a very close call. He's not a first rounder right now. Can he work himself in pre-draft? I suppose. But likely, he is a guy in the 35-45 range. Maybe he gets an NBA cup of coffee, but likely little else. Can staying one more year get him closer to the 20-25 or better range, with more guaranteed money and a better shot of sticking around? Maybe, maybe not. I dont know, and clearly that is what they are trying to figure out too.
That being said, I respect his process here, and if he decides to go, nothing but the best.
Hope he stays though.
