It's pretty simple, actually. He's shooting at roughly the same rate (45% overall this year vs. 44% last year), but he's already played roughly twice as many minutes and taken about twice as many shots as all of last year. So we've seen twice as many misses overall. Of course, he's also averaging roughly twice as many points per game (11.6 this year vs. 6.3 last year). Sounds like it's the same as it ever was, but Doc is using him more because the big man rotation is so thin with injuries.
