I don't know who has been saying that, but I disagree. Is it feasible? Sure. But I highly doubt it happens.
The Sox should, however, sell quite a few pieces. Lester, Koji, AJP, Peavy, & Drew to start. Lackey has an option for next year and would be nice to keep around but if you can get a good return for him (or if you can package him with Lester and get an elite prospect) then dish him.
There will be new veterans on the club next year, but that's because a lot of the veterans are in the last year of their deals this year. Virtually the entire bullpen will be rolled over. Peavy, Ross, AJP, Drew, Lester, Gomes, etc.
I still don't think the Sox will make any huge splashes, though.
Next year, I think the lineup you'll see will be something like this:
Victorino
Bogearts
Pedroia
Ortiz
Napoli
Betts
Cecchini
Vazquez
Bradley Jr
Going to struggle to score runs again, but 2016 could be a massive year.
