The Sox need a Shortstop and the Brewers need to make way for Alcides Escobar.
If the Brewers had some foresight, they could have dealt Hardy during last year's offseason and gotten a very good #2 starting pitcher, which would have them in a much better spot than they are now. Of course hindsight is 20/20 and there is nothing they can do about that now (I personally was a big proponent of moving Hardy last offseason to make way for the defensively superior Escobar to pick up pitching.)
Would the Sawx give up Bowden for Hardy? Would the Brewers feel short changed in that deal? Would they part with Bard? The only plus right now that Bard could bring the Brewers would be as the 2010 closer, unless he reverts back his starter ways at UNC.
