Also have to look at who was available. We're not exactly talking about drafting Bowie instead of Jordan.
Players 3-11: Kanter, Tristan Thompson, Valanciunas, Vesely, Byombo, Knight, Walker, Fredette, Klay Thompson. None of the bigs had much impact in 2011. The PG's were all underwhelming. Thompson at #11 might have been the best of the bunch over the last half of the season (due to getting PT after the Ellis trade). But I wouldn't place him much ahead of Burks (if at all), who we got with the very next pick.
Kanter is a project, but so are all the other bigs. Will Valanciunas be better? Perhaps, but he didn't even play in the NBA last year.
