I would take a flyer on Sabonis for sure. I agree he is a smart player. But he did play in a weak conference. (Actually most conferences in college are weak. ) But I would not give up Vonleh and a #1.
Weaknesses from DraftExpress
"Defensively, Sabonis has a lot of room to grow. Not much of a shot blocker or rim protector in general, his lack of elite quickness and length limits him on this end. He is by no means lead-footed, but has struggled to stay in front of quicker forwards at times over the last two years. He does a decent job defending the post, positioning himself fairly well, but struggles to stay straight up defending shots inside, frequently committing unnecessary fouls as a result of that or when his emotions get the best of him. Not battling quite as hard on this end until shots go up as he does the rest of the game, it will be interesting to see what kind of defensive player Sabonis can be at the next level."
