Oh God, I hope you didn't think I was joining the Tulo bandwagon. Sorry. I can see how you would, given the context of my post.
My point was merely that Buchholz isn't a discussable piece anymore. I can't imagine the Sox trading him for anyone. Maybe for a year and the chance of signing Pujols longterm, probably not for Hanley Ramirez. Yes I'm serious, and don't call me Sherley.
Nothing is more valuable to the Sox than a young power starting pitcher. We know this FO builds itself around run differiental, and we know that SPs play a huge role in run differential. A guy who eats up 200 of the team's 1400 IPs for a season contributes to a good portion of 14% of the defensive production during that time. I say "good portion" because even when a pitcher is on the mound a lot can happen to the team that isn't directly the responsibility of the pitcher... cheap hits, errors, bad calls by the umpire, etc., Still, a good portion is a good portion, if that makes sense.
Look at the list of the top 10 qualified pitchers in the AL by average FB velocity:
1. Verlander, DET, 95.6
2. Jackson, DET, 94.6
3. Burnett, NYY, 94.3
4. Sabathia, NYY, 94.2
5. Beckett, BOS, 94.1
6. Hernandez, SEA, 94.0
7. Greinke, KC, 93.7
8. Lester, BOS, 93.7
9. Garza, TB, 92.9
10. Halladay, TOR, 92.6
Lackey finished 16th and last year Ervin Santana was 5th. In other words, three of the four playoff teams each has at least two starters in the top 10, and the Angels weren't far off. Where would Buchholz rank on this list? At 93.5 he would have ranked just above Garza and Halladay at #9. He's also got one of the best changeups in the game. I'm willing to bet that his value to the Sox lies somewhere in the same range as those pitchers values do to their teams... Greinke, HWSNBN, Garza, Halladay-ish. Those are guys other teams go to get, not guys you move as part of a package. With his youth, upside and cost I would rank him above at least Jackson, Burnett, and Garza, and I could be convinced to rank him above Halladay and Lester overall too.

In terms of shortstop, I think Lowrie and Iglesias will get a shot over the next few years. Alex Gonzalez would be an adequate choice to train those guys up. I think the Sox might be very well suited to trying to just get a great glove and plant him in Boston. I think that's who they hope Iglesias will be. If you can't get an offensively dominant SS, get someone who makes up for it on defense--especially given their pitching heavy philosophy. Shortstops can be remarkably valuable if their defense is above average, as they get so many chances.
Tulo ain't happening.
