Jacksonville is another team that you have been able to pencil in the negatives for a while now. Below are the results of error rate and fielding percentage, two important defense metrics, compared to win total for each team. In most cases shown in Table 1, the Pythagorean prediction of WP is very close to the actual winning proportion, and by extension, the Pythagorean prediction of team wins is usually very close (perhaps within three) to actual team wins.

This means that the Red Sox are statistically expected to be 50-37, four games worse than their actual 54-33 record. For example, if a team scores 75% of the total points and only allowed 25% of the total points throughout the year, would we only expect that team to win just 75% of their games?
