Durham is clearly the best hitter of the bunch. His issues are his glove and staying healthy. You'd need a contingency plan to go with him. Loretta still has a solid glove, but his power has vanished the past two years. The nosediving OPS looks like a red flag to me. Kennedy doesn't look good enough. I just get a bad feeling about Lugo, I can't place it. His speed could make up some for his OPS. I don't know how well he plays second, either. DeRosa has basically had one good year. I'd be worried about overcommitting to somebody like that, but he could repeat what he did last year. Valentin did reinvent himself a bit last year, abandoning the all-or-nothing swing that had stopped working for him and cutting down his strikeouts without a big effect on his power. I can't see him as more than a platoon player, though, so you'd still need to find a righty bat. I like the way Aurilia hits lefties; the Mets could use somebody like that to balance the line-up. And he can play all four infield spots. 500+ AB might be beyond him at this point, though. I think the best options are Durham or a Valentin/Aurilia platoon, depending on who wants what for how many years.
