I think Linebrink/Turnbow could turn a good trade together. Matt Wise is practically worthless so they should get what they can for him. Shouse & Spurling weren't all that terrible, McClung should stay as well.
I'm not sure what they will do with Capuano. Trade? Bullpen? Hope he returns to form in the rotation?
It would be really nice if Sheets could play a full season.
Sheets/Suppan/Parra/Villanueva/Bush or, better yet, an improvement with a signing or trade would be a solid rotation if weird & consistent injuries stay away (Hey Ben).
No offensive upgrades really needed. Jenkins and Koskie will both be gone & won't be terribly missed. Will any team give Jenkins that kind of money? Milwaukee should try to keep a third catcher in the majors next year, there were plenty of times when a switch would have been good but Yost didn't want to risk being without a backup.
