I only saw Zoubek play for 2-3 minutes but he looked like a poor man's version of James Augustine to me.
Augustine is becoming a fairly decent player.
Players like Zoubek only have a very marginal place in today's NBA. The game is too fast and too quick for this type of big man. I wouldn't waste a draft pick on him, there's no upside in him and you can only grab similar players through a D-League call-up or something. I like the way he sets screens, but I'd be worried he'd hurt someone in practice.
