I have not been one of the commenters who wants to trade for Garza. I think he would be a nice addition to our team but the asking price is most likely insane and not worth it. He is not a #1, and probably not a #2. But he would give us a quality starting option in our rotation after Chen and Hammel. Forget about the asking price for this comment and take this into account.
What I have been thinking about is that a trade for Garza now would put us in a good situation come the start of 2013. Hammel, Garza, Chen, Wada, Britton. Arrieta, Tillman, and Hunter could all be dominant relievers in one inning stints IMO. If we are sellers, Hammel, Garza, ad Wada could each give us hefty returns. If we are buyers, we can keep them all and try for a shot at the playoffs with potentially 5 quality starters. Of course anything could happen between now and the trade deadline of 2013, but I thought it was worth discussing.
