It's not specifically seeking out only a shortstop. It's not limiting your options. My argument is that moving Theriot to second if we can find a good upgrade at SS should not be ruled out. The goal, however, is not to move Theriot to second. The goal is to upgrade SS and then keep Theriot in the lineup by moving him to second. We can also platoon Theriot and Fontenot at second and then either use Baker as a super-sub, trade him or let him walk and save some money. In his career, Theriot has OPSd .824 against lefties. Baker has done better, but with his terrific numbers as a Cub this year, he might have more trade value than Theriot (though neither would have a lot). There's also the option of finding a SS upgrade, platooning Baker/Fontenot and trading Theriot. It's all about having as many options as possible when our overall options are limited as it is. Refusing to move Theriot to second further limits our options needlessly. I don't really think there should be any sort of goal involving keeping Theriot in the lineup. In 2 of his 3 full seasons, he has been a rather lackluster hitter, he's not a good fielder and he turns 30 in a couple months, which indicates his usefulness as a middle infielder may be dwindling soon as he loses whatever step he had on the competition. If you can't find a better replacement, so be it, but they should try.
