Starting in 2007, he appears to have made the shift to a full-time OFer. He hasn't played 2b with any regularity at all since 2008. Putting him back at 2b would likely yield some very nasty results on defense.
But man, if you could get him to where he was just a slightly below average 2b, the damage he could do on the basepaths would be a hell of a lot of fun to watch.
It's my own fault for expecting the Titanic to beat the iceberg this year.
