The problem is not Dunn, The bigger problem is Konerko. You need 2 things from your 3-4-5, hits (preferably HR) and RBIs. Station to Station baseball is not the result of the heart of your order, its the result of lack of talent surrounding it. This year, we had poor offensive production from 3b, 2b, LF, and only average production from SS, CF and 1b.
when 2/3 of your lineup is Average at best, you are screwed.
