The question I seek to answer today is how much value Manny should prospectively provide the Pale Hose. Dave Cameron saw the difference between Manny and Mark Kotsay as worth about 8.0 runs per about 100 plate appearances.

… Let’s take a look at some other famous Cooper turnaround efforts, beginning with the two players the pitching coach himself was quickest to cite:
