No argument from me, but all the signs of his ability point to the possibility that he was a victim of excellent defensive play, not poor baserunning. The game engine will also not let him accurately take the extra base above league average with a PR rating. To each his own on this one, but imo the rating is too severe, I would adjust it.

timz made a good point, when I rate players, unless there was an injury I DO take into account a 3-4 year window of their ability. I don't rate a player a FR bunter when he had 25 sacrifices the year before and only 3 this year because he was used in a different role. Andrus is a rookie, but with his skill set and breakdown of running stats, he'd get an AV rating from me. Can't see him holding up on 80% of his opportunities to take the extra base when he took it half the time. To me that's not realistic.
