Here's what I see happening:
SS: Sox sign Lugo. Sox fans won't fall in love with him and won't be patient if he sucks, but his speed is exciting and he has a little pop and certainly isn't BAD in the field.
CP: Sox try to work out a deal for Brad Lidge or Aaron Heilman. They hold on to Keith Foulke and have Hansen as the 3rd option.
SP: They push very hard to land one of the big 3. I get the sense that they're serious about Matsuzaka, partcularly since, when it comes down to it, he's a risk that is only really feesable for a big money team. I believe the mariners rumors I have read about them not being all that interested. Like someone else mentioned here earlier, Schmdt would probably be a similar salary but you know what you're getting and you don't have to pay the outrageous posting fee. Personally, I'd be excited about next year if we got either of them. Schilling, Beckett, Schmidt/Matsuzaka, Papelbon, Wakefield would be a fine rotation. If Lester's around either use him as long relief or put him in Wakefeld's spot (probably the latter).
OF: I am starting to doubt that the sox are going to move Manny. I'm actually pretty confused as to what direction they're going in with their zip-loc seal on the FO's goings-ons. If we keep Manny then get Ramirez (Aramis) and send Lowell plus most of his salary for a young OF option. If you move Manny (say for Heilman and Milledge) then Milledge or Crisp becomes your 4th OF, each of them having something to offer. Line Ellsbury up behind Milledge and you're looking at a nice core of young OFs in Crisp, Ellsbury, Milledge and Wily Mo. This would be particularly so if Milledge continues to develop power like some beleve he will.
We're talking about a savy team here. They can make deals happen, but the more they try to be stingy the more they run the risk of having deals slip out of their grasp. I think if they go in 15% more aggressvely than the past few years they will pull off a number of good moves, expected or completely out of the blue.
Pedroia; the word on Pedroia from what I've seen and heard and read is that he's a high OBP guy. He's very small and has a good eye. He also has decent gap power but nothing substantial (i.e., the ball will go to the gaps but not absolute rockets). He is a great fielder with only limited range, which is why many argue about the claim that he is capable of playing SS. From what I observed during his brief stint with the sox it looked a little overwhelming for him at SS, but he looked more than competant at 2B, partcularly with the DP ball and working with Gonzo/Cora (both excellent fielders). He's a scrappy leader type player, and he will probably become a fan favorte without much difficulty after a few good games. He had a tremendous career at Arizona State.
