Agreed that you need help at SP. Having Od. Perez as your #1 is not good as he is more of a #3 starter. Lidge, Cordero, and Benitez are top closers, so you should deal those guys away for SP and acquire middle-tier closes in Dotel/Ryan/Takatsu/Kolb etc, If you land guys like Halladay/Beckett (or Peavy/Sheets like somebody said earlier) your pitching will be even and lethal.
Fix your SP, and your good 2 go
