As far as CC only being worth 2 wins. I don't know how anyone can believe there is a valid way to quantify something like that. There is just too much variance in both the ripple effect and the very unique circumstances each player goes to that make each case different. There most certainly are valid ways to estimate a players impact. Although, I don't think Russ is selling his results as anything more than an approximation. Generally speaking -- if you replace a league average player (Jorgenson Marlins), with a MVP caliber player (Ryan Howard MVP season) you net about 5 wins. CC is a MVP caliber player, McClung is a league average player, so for half of a season, it is certainly historically reasonable to conclude that CC will give us 2-3 additional wins. McClung has started 8 games for the Brewers, we are 6-2 in his starts, one of the losses, the Brewers only scored 1 run. CC would probably have lost that game as well. The other loss (6-7), McClung gave up 5ER and CC would have probably faired better. So in 8 starts, the Brewers would have picked up 1 win or so, again Russ's estimate seems reasonable. In Bush's last 8 starts the Brewers are 5-3 (The 3 losses, 6-3, 10-2, 7-2. Bush gave up 4, 3, 5 ERs) -- as we can see -- the Brewers offense didn't help much in these games, in one game the BP gave up 7 ER -- both factors that are out of the SP's control. Could CC done better than Bush? most probably yes, would he have won all three games? -- probably not -- I think CC may have won 1.5 of them that Bush didn't -- again Russ's estimate seems fair. We had this same discussion when Yo got hurt. The loss of Yo sucked, but Russ told us, it would be a 3-4 game differential over the course of the year -- and for the most part, I think if you look at what the Brewers have done since Yo's injury, we have probably at most lost 1-2 games so far with the Brewers losing Yo. Losing Yo is probably going to have about the same net effect as adding CC. Additionally I think people are horribly undervaluing 2 wins for a team in the 85-95 win threshold. Most of your playoff teams are going to fall in that 85-95 win range, being able to slide up 2 wins when your playoff team pool is jammed in a 10 win range is really huge. This is a lot like saying you give a horse a 2 length advantage in a competitive race.
