Re: Could the Reds have possibly gotten more for Sean Casey and Wily Mo Pena?
I don't think so. Not for WMP -- believe it or not, many nonparial non-reds/Red Sox fans I've talked to have been very surprised the Reds were able to have a straight-up trade for Arroyo. Casey, after all, was not a straight-up trade. I still think that was partially a salary dump, and given the timing and Casey's age, a pretty wise one.
There is no such thing as a pitching prospect.
