The Sox have a lot of different things they can do. But to me, the dealbreaker with me is that they shouldn't trade Middlebrooks.
Who knows, maybe Middlebrooks won't work out. But he's played seven full months in the majors, and five of them have been very good. If you combine his partial months, including the postseason, he's been good in five of eight months.
When he came back in August, he showed better plate discipline too. And while he remains a work in progress defensively, the work he did with Mike Lowell in the spring on footwork an throwing helped.
Middlebrooks is a right-handed power hitter with power to all fields, and the Sox haven't been very good recently in develping power hitters. You don't give up on that this quickly, especially if he can play third base.
As for others:
Salty? Would like him back, but if the Sox move on from him -- so be it.
Napoli? Would like him back, but I could handle Middlebrooks to 1B, Bogaerts to 3B and Drew at SS. Not ideal, but ...
Drew? Would prefer an infield of Middlebrooks, Bogaerts, Pedroia and Napoli, so I don't really want him back. But I if Napoli leaves, I'd accept the above scenario.
There's talk about bringing all six starters back for the spring. Could see that. If they trade any of them, I'd want them to trade Peavy or Dempster even though I like both. There's talk of trading one of the others because you could get more for them, but to me, I want to keep the best pitchers. The Sox have no glaring holes that they need to make a blockbuster deal. And they better not trade Lester or Buchholz like some have suggested, but I don't think they will so that's why they aren't on my must list.
So in the end, they better keep Middlebrooks. The rest is fluid.
