Sounds EXACTLY like the talk with Tomislav last year.Andrej could come back next year, yes, but I would expect him to make the jump to the NBA. Never say never though.
I do think Andrej has a better year, but considering he's a poor shooter, he's likely not gonna get first round grades.
If he were to leave, then it's probably going to end up a Henry Vessar type decision. Nothing wrong with it, just comes down to is that what he prefers.
