We'll have to see him play it out, Dipre, but frankly, I see no reason not to believe he is EXACTLY this good. The minor league numbers bear out his potential, and he started the surge he's on right now in the middle of last year. There was a point in the ALCS where he couldn't not hit a homer against us. Him and Aybar and Upton all murdered us -- the difference is that Zobrist sustained it.
He's got the discipline, he's got the power, he's got useful speed, he's got the OBP. His bat compared to Youkilis this year. And Zobrist switch hits. All he needs to do to disabuse you of your "career year" notion is keep his average up (his .330 BABIP is on the high side, which is about the only legitimate concern).
And his position versatility puts him in the conversation for one of the best players in the American League. I donno if he's as valuable as Pujols, but then guys like Pujols happen actually more often than the kind of truly super-versatile power hitter Zobrist is emerging as, so... *shrug*
