I wanna kick the tires on what it would take to get Reid Detmers and Sam Bachman. That would, effectively, get us two relievers as one of Mikolas, Littell, or Alvarez/Irvin would have to go to the pen. That, effectively, replaces Parker and Schultz with Alvarez and (probably) Mikolas, which should be an improvement of they limit Mikolas to 1 inning relief spurts.
With Vivas and Mead playing well, House becomes tradeable. I think a package of Susana, House, DFG, Dickerson, and one of Franklin, Pickney, or James gets it done. Or at least gets a serious counter.
