this is a solid team all around.
the only problem i see is that you have ALOT of risky guys who probably won't all pan out, which i'm guessing you're aware of:
lieberthal (injury risk)
juan gone (injury risk)
matsui (japan transition)
wigginton (semi rookie)
now even if about half of these guys provide value, i would advise trading away some of the hype in return for dependable stats. seems it would be possible to trade matsui/juan gone for, say, a garrett anderson or jim edmonds (always underrated). moves like that would be great for your overall security.
