If Cameron did save 20 runs over the average CF, he made each pitcher slightly better, no doubt. However, if they sign someone who projects to a 4 ERA, and they take the place of someone projected to have a 5 ERA, that's 22.2 runs saved, over 200 innings. Considering Mike is not a youngster, and both his offensive and defensive output is projected to fall based on age alone, I'd go with a cheaper replacement myself. I like Mike, and would be happy if he said he'd be back for $4M, probably even $6M. My guess is, he'd be willing to take 2y/$20M rather than the $12M he'd get in arby.
