Theriot's production is no guarantee either, and it remains to be seen if he has an OPS over 720. He's just 2 seasons removed from a 672 OPS, last year was 712, and is now 30. We've seen his peak, and it's highly likely he won't be back there again. He likely won't be a .745 OPS guy, but I don't know that he's likely to regress that much. A .710-.720 OPS is probably a solid bet for him. I'd love it if Castro could match that, but it's not likely. When you're talking about guy coming off 712, with a goal to be 710-720, then sub 700 is hardly a stretch. Well sure, but on the flip side, a .730+ OPS is possible as well. I'm not saying Theriot will definitely be better than Castro, I'm saying that Castro being as good as Theriot is far from a guarantee. In fact, the likelihood is that Theriot will be the superior offensive player. Is that a certainty? Of course not. But my post is in response to the idea that Castro is guaranteed to be as good or better than Theriot and that's not accurate.
