If Bobby V is out, and 1st base is open, and there aren't great 1st basemen free agent options, aside from Napoli, then why hasn't there been any talk of Youk coming back to Boston?
I believe he's a free agent this winter. It seems logical to think that he's on the decline. It also seems better for him to be playing first, and a fresh start could turn him back in the right direction.
I'm not saying I love this idea, nor that I think it'll happen. It's just a thought.
