That's a great team because where on position might be weak (BA in OF where the power is great) it's boosted by another position, like the BA of your C and 1B being so great. I don't think you a hole, except praying Nomar doesn't get hurt.
That is a GREAT team. I don't think you're going to have any problem winning if you stick to your guns. One possibility, coming from a Cubs fan, might be to drop Borowski for Saito. Saito is pretty much the guy right now, and Borowski is either on or off. He's been decent lately, but I like Saito a little better. Maybe find room for C Guillen as a back-up for Garciaparra in case he gets injured?
