Very weak outfield. Weak rotation after Beckett. Horrid bench. It's in your best interest to dump the Arroyo's, Lilly's and Millwoods, for low risk, high upside guys, like Matsuzaka, or Bedard, or rookies about to break onto the scene.. Buchholz? Matsuz?
If I were you, I'd trade Howard for whoever has Billy Butler, and their best OF.
