And those plays are countered by him throwing the ball away about 10 times a year more than the next third baseman. It all evens out, hence why he's had back to back negative UZR and DRS seasons. Couple that with a history of shoulder and throwing issues and it's pretty clear that he isn't long for the hot corner.
Actually his # of errors and games played in 2010 and 2012 are damn near identical. I don't know what this means, but it's worth noting. Seems like if his massive dropoff in UZR was because of throwing, he should have had a lot more errors.
