The defense is a damn mess. On some level we just have to accept it a bit and try and outhit the other team. Solving it is further complicated with the addition of Kirk. If he DH's a lot it allows Jansen, who is our best defensive player, more PT at a key position. But that only adds to the glut of DH types who then need to take the field to get AB's which includes Kirk, Vlad Jr., Tellez, Teoscar, Lourdes, Shaw, Fisher, etc.
Perhaps we could acquire a good defensive 3B and CFer and then release Fisher, release/bench Shaw and trade Tellez. That leaves Vlad, Gurriel, Teoscar, and Kirk vying for AB's among DH, 1B, C, and LF but that's probably fine. Then pray that Bo, Biggio and Vlad Jr. (he'll never be good but he could go from atrocious to borderline playable) improve defensively.
The other option is to just say f*** it and go all out for offense.
