VHSL Football - 2005 Division 4 Pythagorean Expectations

A Pythagorean (expectation) projection is an approximation of each team’s wins based solely on points scored and allowed. The concept was first used by Bill James, an influential baseball writer and statistician, who found that a team’s record was very closely correlated by taking the square of the team’s runs scored and dividing it by the square of the team’s runs plus the square of the team’s runs allowed.

Statistician Daryl Morey of STATS, Inc., later adapted this formula for professional football using 2.37 and I further found that the exponent 2.7 works better for VHSL football.
I applied this formula to each team and found out which teams are out performing their projected winning percentage and which ones were under performing.

The key is as follows: W = Actual wins L = Actual losses  PFALL = Points for  PAALL = Points against  Projected W = Projected Wins  Projected L = Projected Losses  
Win Difference is computed by calculating the number of wins the formula computed (Projected W) and subtracting that from the number of actual wins (Actual W).
A positive number means the team had more wins that the formula expected, a negative numbers means less wins than expected.
