How optimistic are fans?

By Tangotiger, 04:00 PM

I posted at Fangraphs:

Fangraphs shows 220 non-pitchers with Fan forecasts.  The total WAR of those players forecasted is 685 wins.  With my personal forecasts, I have those exact players at 496 wins. 

Seeing that all non-pitchers in 2009 came in at just under 600 wins, and seeing that there were nearly 700 non-pitchers in 2009 (meaning that there are plenty of players still left to be forecasted), my personal forecast probably serves as a reasonable baseline.

On that basis, Fans are expecting 38% more marginal wins than will be generated.  That works out so that the average team wins about 94 games.

Hope truly springs eternal, as everyone thinks they are a playoff contender.  Not to worry though.  At some point, the Fan forecasts will be recalibrated to knock out the optimism, so that the total WAR (nonpitchers + pitchers) will come in around 1000.
