Actually, he does remind me of Darko.
Perhaps because he's white and his origins are in ex-Yugoslavia (Croatia, Darko comes from Serbia). But in terms of skills and athleticism, Darko is light years ahead of him ("Please turn off your BS detectors.") He's quick, fast and with extremely good vertical leap and is not as raw as people think he is, even though he's still riding Brown's bench. I saw him play in Serbian league and if Kwame was considered raw (which he still is), then Darko was already Duncan-like at seventeen.
And about Bogut: he's a skilled, big hustler who doesn't run away when he's being touched (hum, just ignore the homofobic potential). IMHO, that's a good combination. He'll never be a superstar, but I can see him as a rich man's Vlade Divac (less whining, more hustle).
