Yeah I think his profile does typically age poorly BUT I would be more concerned about that if we were talking about a big 5 or 6 year deal.
His OF defense is much maligned, but I think it's to the point that his defense is actually underrated. He's not a pure DH, he can play a passable corner OF. His base running is similar.
He's got a great body (pause) and good physical tools. You'd also normally be concerned about those declining as well but his sprint speed is the same now as it was when he was 24; he seems to keep himself in good shape.
I'd be game for a Lourdes-type contract.
