I don't totally agree with this but if somewhat true than I feel like WAR (Wins Above Replacement) is being treated like the 2nd coming of Jesus. Current baseball statheads put WAY too much faith in that stat, IMHO. WAR definitely isn't perfect, especially for pitchers. The issue is there really isn't a perfect single stat you can use. WAR is something you go to because it is an objective measure with one single value so it is just easy to use.
