My only concern about Wacha is his durability. No doubt he's a very good pitcher, but will he be available every 5th day? He's definitely worth taking a chance on going into the future. It ain't like the SOX have a closet full of talented young pitchers waiting in the wings.
Here's a thought. Maybe the SOX FO priority right now s/b to try to sign Dugo to a long extension. He's the 2nd best hitter on the team and he's only going to get better. It wasn't his fault that he was part of the irreplaceable Betts' trade.
