The only positive I see to starting Barney is that he's a plus defender (from everything I've heard). At the same time, there is no plus part of DeWitt's game. He's better offensively overall than Barney, but isn't particularly good either. Thus, since you're going with a young guy anyway, the reasoning would be to go with the guy that already features a plus skill and hope the other side comes around enough. Barney, it sounds like, is Theriot with much better defense and a slightly worse bat. That said, I'd prefer to go with DeWitt. Both are young but DeWitt has shown more offensive potential. With Aramis, Starlin and Pena around the infield, we have good to very good defense at 3 of 4 positions and can afford to put up with poor 2B defense with the hopes that DeWitt's bat comes around. Exactly.
