Outfield defense is a BIG worry. Beltran is out at least a month and may be compromised when he gets back. With Bay, you hope he hits well enough so that people don't notice his fielding. Francoeur's arm may cancel out his below-average range, or it may not. Pagan will be average in center, which may or may not be good enough to make up for the corners. I think Citi will be a much bigger issue for outfield defense than for hitting home runs. The infield depends a lot on Reyes. Cora and Castillo aren't the plus defenders they used to be, and Wright is up and down. Murphy is better than his rep, assuming he starts at first. I think we'll be average at least in the infield if Jose stays healthy, but I wouldn't get excited about it. So yeah, I'm worried, especially with Beltran out.
