Derrick Rose is, in my opinion, one of the most overrated players in the league right now. He'll eventually be good enough to warrant the hype he's getting, but right now he's nowhere close.
He's inefficient because he doesn't get to the line (unless he's playing the Celtics), he still struggles from outside, he's not a very good passer for a point guard and he doesn't play defense. People see his jump-thirty-feet-in-the-air-up-and-under moves and think "WHOA! MVP!!!". He's a freak athlete and he makes some spectacular plays, but there's more to being a dominant player than that.
