Here are the keys according to my worthless opinion:
Calhoun catches fire (Had Figgins just gotten warm in 2009, we would have two rings, IMO).
CJW pulls his Head n Shoulders out of his ass and is, at the very least, serviceable.
Shoemaker comes back and pounds the strike zone, maintains his aggressive approach, controls counts.
Freese channels his inner Redbird.
Weaver steps up, avoids big innings. Limits the bombs.
