When it comes to big games against longer players like Gasol or Bynum, I disagree. This is no different than Memo who held his ground well and tried to play good team d. But when push came to shove, he simply didn't have the ability to truly challenge the offensive player whether that meant blocking a shot, altering one, or gaining any type of psychological advantage in the match-up.
Kanter may be listed at 6'11 (without shoes) and he may rebound at a very good rate in the NBA. But he doesn't appear to have the lift or play tall to truly challenge the best in the league. Against heavy-footed guys like Kaman and maybe Bogut, he may be okay. Against Howard, Bynum, the Gasols, and maybe a few others, I'm not so sure. The bottom line though is he's 19 so if you're someone like me, why worry. We have the luxury of time and a stable of bigs, specifically Favors, who I believe can play truly big at the 5 if Kanter can't.
I agree Favors can be 5 and Kanter 4, but tell me who can defend Gasol, Howard ,Bynum without any problems. Also Kanter guarded Marc Gasol pretty well against Spain
