In last year's study, I found a .88 correlation between Wins Above Replacement and actual wins. This year is a slightly different story, but WAR still shows as a telling statistic.
WAR is a heavily debated statistic. There's controversy over which version of WAR is better -- BP, FanGraphs, or BR -- and there's debate about whether or not ERA, FIP, or xFIP should be used to calculate WAR for pitchers. The following study uses fWAR.
As much debate as there is, WAR is a fairly accurate predictor of a team's record even with the inconsistencies and flaws in some of the stats.
