Now, Ryan Theriot has a lot of qualities that lend toward being likable, but he's also not very good at baseball. I think that what's happening here is that a lot of fans remember how poor he was last September, are combining it with his slow start and coming to the conclusion that whatever magic Theriot once possessed, he no longer has. It's not necessarily the correct conclusion, even if it agrees with the correct conclusion - Theriot never had any magic to begin with.
So I'm torn - part of me agrees with T.S. Eliot: "The last temptation is the greatest treason; to do the right thing, for the wrong reason." On the other hand, there's much to like in what Winston Churchill said: "If Hitler invaded hell, I would make at least a favorable reference to the Devil in the House of Commons."
But the only opinion that really matters is that of the Cubs braintrust, specifically Lou Piniella and Jim Hendry. And I've seen no indication that they're souring on Theriot just yet. That makes sense - they're more likely to try and sort through these things rationally than fans, who by-and-large tend to experience these things emotionally first and foremost. And obviously the Cubs organization thinks they know something about Ryan Theriot's true talent level that I don't. But this bears watching nonetheless.
