Already eliminated Liriano/Joba/Harden/Sheets/Fuentes/BJRyan/Rivera and Bobby Abreu
Was thinking about packaging a 2B, but with Utley out til June, I think Kinsler stays. Utley will be a nice midseason UTIL upgrade; or Kinsler gets me a stud SP this summer. With Bay returning to 100-30-100-10 status, and moving to Boston, it would be tough to let him go, even if OFs are easier to replace.
Would Papelbon and Fielder for Pujols be good? I worry about Pujols' health.
Quentin definately is out. He has not proven enough to be a keeper yet. As of now, he is a one hit wonder. That's not to say he won't do it again. I would keep Papelbon even though his saves were a little down. Like you said, you could probably package him in a trade.
A two for one with Paps included is the way to go. I think Paps and Fielder for Pujols sounds good.
For an alternative opinion on who to drop, I would suggest Kinsler. You know Paps is good for 40 saves. Utley will return in June, you can plug the gap until then.
