Geez -- This is a great signing for the sox, which I hate as a Rays fan
...and I as a Yankee fan. Boston is being pretty damn shrewd this offseason.
Of course, as Yoda mentioned, this could end up becoming a team decimated by injuries.
Couple that with the possible fluke 08 seasons by Youk, Pedroia, and Lester, and this team could end up either winning it all or missing the playoffs and I wouldn't be surprised by either. Should be an interesting AL East this year, to say the least.
