Is Troy Tulowitzki on the Toronto super roids?

I can't figure it out. He's ruining most fantasy leagues' playoffs, he's got the Rockies as contenders in the NL West, and he's suddenly a strong MVP candidate. I've always thought Tulo was a good player, but this is absurd. Has anyone ever carried their team like Tulo is doing right now? He just had another multi home run game today! Why do teams even bother pitching to him at this point? If you walk him and Carlos Gonzalez the Rockies have no one who can really beat you with their bat.
