The problem is that Stroman/Sanchez don't have all that much team control left. I don't think it would make much sense to trade for either of them unless they agreed to sign an extension. The Sox will almost certainly have to trade for a pitcher at some point, but I'd aim for one who is under control for longer. I thought Luis Castillo of the Reds would have been a good fit if they wanted to make a move this past offseason but that ship has definitely sailed.
