Wow. You're judging the guy with such little information. You just seem determined not to like him, for some reason.
As for Nikola Vucevic, he's a big guy, but he's not nearly as quick or mobile as Kanter, and he doesn't appear to be as strong, despite the extra weight. He seems pretty skilled, but he doesn't have nearly the upside Kanter does.
Nikola on a playoff team > Kanter on a lottery team.
