I hate to say it, but I beginning to think Theriot might suck. He only appears to be a slightly better hitter then Iz, and he has no range. I would keep Iz at SS and at the 8 spot everyday, and then figure out who the super sub is between Dero and Ryan. In each of his last 3 seasons in the minors, his OBP was .367, .365, .367. So he's got that going for him, which is a heck of a lot more than Izturis can say. That translates to, what, .335 in the bigs? Izturis' defense might just be enough to make up that difference. I'd say there's an argument to be made that they are about equal players.
