Have you looked at his stats? If he could come anything close to his 2005 he would be 3x the hitter Theriot is, and they are equal in the field, Lopez may even be better. I'm not sure where you get the idea that Lopez is the defensive equal of Ryan Theriot, but defensive systems that use play-by-play data (which BP doesn't) like PMR and Fielding Bible's +/- seem to agree that Theriot is solidly average while Lopez has been one of the worst fielding SS's in baseball over the last several years. His awful defense was pretty much the justification for the Reds trading him in the first place, despite a very good year at the plate in 2005. He is clearly not a SS. Not sure how he would perform at 2B. Offensively, at his best, he seems like a poor man's Brian Roberts. He's a switch hitter with speed, so you can see why Jimbo might like him, but I doubt he'd be an upgrade over DeRosa. He also seems to have a bit of an attitude of problem. It sounds like he is going to sulk on the bench if he doesn't get to play every day. BP had Theriot as a -6 SS last year, and projects him to be -4 this year, that's not average. Lopez was -12 last year, and was as high as -5 in Cinci, and they project him to be -4 this year. Neither are great options, and Lopez will make up for it a ton more than Theriot will with the bat. Once again, I'm not sure why you would trust BP's defensive stats which estimate how many plays a fielder should make based on a variety factors (pitching staff, balls in play, baserunners, etc.) over newer, more advanced systems that actually use batted ball data. Not to say these metrics are infallible, but they seem to agree with the general consensus that Felipe Lopez is a third baseman playing shortstop. Likewise, Theriot, if you watched him last year, seemed to make all the plays he was supposed to make. That pretty much jibes exactly with the data. Not to mention that he was one of the better SS's in baseball at converting DP opportunities. He was not gold glove caliber and his defense might not be good enough to overcome his bat, but he was not a poor fielder. Whatever, he just doesn't impress me with any part of his game and I don't know how it would be that hard to replace him, hell I have practiced with the guy and no part of his game stood out when I was playing with him, I don't understand how he is a major leaguer that has no real threat to his job security. He's decent, and I think off the bench he could be pretty good but playing every day he could be a major weak spot. I just wish that they would give DeRosa a chance to play SS and trade for Roberts, or trade for an every day SS. How many of the other major contenders have a weak spot as big as the Cubs at SS? Not to mention we are also taking huge risks by going with rookies at CF and C, basically three eighths of our lineup could potentially be black holes. I doubt Soto will be bad but you never know.
