here's how I see it: if he had a reason to stay in the draft - i.e. a firm promise - he would've already declared he's staying in...no?
there really wouldn't be any benefit for him to hide the decision to stay in the draft if he has laready made that call...right?
looks like he is hoping to get that promise in the last hour...which, if he doesn't have one by now, good chances he won't get one in the next couple of days...but it is possible...
I'd guess his chances of returning to NCAA next season are greater than 50%
