Wins Above Replacement, or WAR, is newest win-based stat of choice (I’m still a fan of WPA, too). I wrote about the difference WAR can make for particular players earlier this week, and I got to wondering how it did overall. Me being me, I graphed it.
Here’s a graph of WAR (on the x axis) and WSAB (on the y) for all position players from 1900 to 2008:
As you can see, the two stats not only track very closely, but they almost intersect at zero (I divided WSAB by three to make them equivalent to the WAR scale). If you’re a math nut, the R squared between the two is .96. That’s the good news.
However, as I showed the other day, the difference between WAR and WSAB can matter a lot for individual players. Also, the variance between the two is greater for individual seasons, as you would expect. That’s the more discerning news.
I’ve got no other point. Just thought you’d like to know.
