And I am ok with projections. When you made it dogma I have issues. That's the point. You want to do projections, try the projections for the 2015 season and see how accurate it was to what really happened.
I never presented it as dogma. Here was my original post that started the conversation:
Carson Cistulli of Fangraphs has posted a Cubs depth chart with fWAR values. It's kind of insane and if my math is right the projection is 97 wins.

After that I mentioned that I didn't realize the correlation between WAR and actual wins was as high as it was until someone pointed it out to me with the Cubs example. Since then we've been mired in semantics and a back and forth on whether we were talking about projections or correlations to actual data. At one point you said there was no correlation and that was obviously false. There is a correlation in the actual numbers which makes for a useful projection tool.
As far as comparing projections to actual data, I've done that exercise before with past seasons. Typically overall win totals for teams end up being somewhere between 65% and 80% depending on who's projections you're looking at. ZiPS is usually one of the highest of those projections year after year but I'm certain there are examples where they were horribly wrong. If there was a perfect tool we would all be rich and Vegas would be bankrupt.
One of the things that has made baseball more fun over the last 20 years is the fact that statistics have improved. You can make projections based on data rather than simply by the eye test. Of course those that ignore the eye test do so at their peril as that will always be part of the game. Along with statistics come better ways to project future performance as opposed to going solely on past performance which has led to some of the worst contracts in baseball history. Some teams haven't learned those lessons but some have. Even the ones that have can make mistakes. The great contrast in baseball is it is at once the most statistically inclined of all the sports, in other words there are very few areas of the games where solid data is not available, while at the same time being one of the most unpredictable. Baseball is going to baseball. It's fun to study stats, it's fun to watch the games. Nobody, no matter how informed, knows everything.
