Silver knows it’s been tougher to figure out the White Sox than a presidential election. PECOTA badly missed predicting the 2005 World Champs, forecasting a mere 80 wins. Next, BP shorted the Sox in ‘06 before nailing their performance in ‘07 - a year everthing went horribly wrong. Last season, the Sox again whipped PECOTA’s projections and contributed significantly to the system’s first historical increase in average error predicting team wins. On average, PECOTA now blows its forecasts by an averge of 8.5 wins, ending a steady trend toward increasing accuracy with a rude blemish.
