The FA market isn't that great this year. They could sign a few short term deals for 2012 and try to make a big splash in 2013, when their top tier MiLB talent is ready, and Kemp, Ethier, Wright, Cain, Greinke, Hamels, Haren, Marcum all become FAs.
I'm not saying give up on 2012, I just don't think they should make any rash decisions and sign mid-level players to exorbitant deals.
