I do appreciate the thread, and I also think this team needs to be blown up. It will start at the top with guys like Beckett, and Youkilis that are ripping this team apart. As mediocre as Dice-k is, I would seriously bet that someone will want him come the trade deadline. Maybe a team like Toronto that is desperate for any sort of pitching depth.
I'd love to see the Red Sox manage to pry elite prospects away from a team for guys like Ellsbury or Bailey who can't seem to stay healthy to save their lives.
Lester has to be as close to untouchable as they come on this team. It would take two elite-elite pitching prospects to get him off this team's hands, at the bare minimum. In my opinion, Jon Lester's contract makes him nearly as valuable as Felix Hernandez, perhaps more so. He's having a bad season, but it happens to everyone. Getting rid of Beckett should be the priority here, not Lester.
Some players to add to the list:
Kelly Shoppach: He's been OPSing .920 against right handed hitters this year, and he seriously wants more playing time. He's also far better than Salty defensively, and not coming back to Boston next year. He could possibly net a very solid mid tier prospect for one of the many contending teams lacking pitching depth.
Atchison, Albers, Miller: I've talked about it at length here this year, but there have been tons and tons of injuries to upper tier relief pitching this year. These guys have had deceptively good seasons this year, but there is always going to be that team that makes a dumb move to try to build relief pitching for a deep playoff run. Package one or two of these guys, and maybe use one of the catchers, and who knows, you may be able to pull away a good prospect. And to a lesser extent, you could probably throw in Tazawa, Mortensen, Wilson, Melancon and see what deals stick
