There is actually a 0% chance of this happening. No chance at all, whatsoever.
The Sox will acquire two of these three pitchers this offseason: Lester, Hamels, Shields.
I would guarantee they get AT LEAST one of Lester and Hamels, and then compliment that with a Shields, Cueto, Zimmerman type.
The Sox rotation going into 2015 will be Lester/Hamels - Hamels/Shields/Cueto/Zimmermann - Buchholz - Kelly - RDLR.
Depth will be Henry Owens, Brian Johnson, Ranaudo, Barnes.
Bullpen will include both Workman and Webster, along with Taz, Uehara, Badenhop, Mujica, and a lefty (Miller?). Solid pen.
