Your team is solid although I'd definitely look to upgrade the RP. Somebody like Mike Gonzalez, who has alot of ability, should be a solid RP/closer for years to come. Brett Boone has slipped drastically ever since it appeared he went off the juice. I don't think a change of scenery will do much for him. A young guy like Bill Hall who has ability and position eligibility is a good guy to slide around your infield if he's available.
I could be wrong in what I'm saying but I'll be dead before I realize it.
