Offensively he's produced less each season. The year he played the most he produced less than the previous years. That doesn't seem like a guy who's suddenly going to improve when past his prime physically. He'll have value as a defender and on the bases. But given he got on base less each season, that value is somewhat mitigated. He's a good part time player because he adds value on defense and isn't a black hole on offense...yet. I just don't see a guy who's on base percentage peaked at .321, and went down every season since, suddenly turning it around after age 30.
