Good lord, trade the farm and get him. Please do it! Giancarlo + Harper + Zimm + Ramos + Desmond + Moore = ULTRA POWUH!
Yeah, I really like Jackson, but I'd be really happy with Shields as the number 4.
I'd even throw in Detwiler to that mix. If only Flores or Solano had shown that they were MLB catchers ... or if Rendon had actually played this season ...
