Matas is an interesting prospect. His athleticism is his best trait, but I'm not sure how athletic he can be with the ball in his hands as his dribble is high and his shot isnt good enough (currently) to make his dribble a threat. I can see the AK influence but he doesnt have the insane length to really be an AK. I think he probably averages a block per game for most of his career.
I could see him really filling out to 215-220ish and being a really really strong athlete. He's thin, but he has a nice frame.
