To explain the columns below, Median is a median point spread, and can be used to get a feel for how good a team is without overly weighting a blowout win or blowout loss. HS is Brian Burke’s Homemade Sagarin, as implemented in Maggie Xiong’s PDL::Stats. Pred is the predicted Pythagorean expectation. The exponent for this measure is fitted to the data set itself. SOS, SRS, and MOV are the simple ranking components. MOV is margin of victory, or point spread divided by games played. SOS is strength of schedule. SRS is the simple ranking.
Green Bay, Baltimore, and New England have the largest median point spreads currently. San Francisco has the largest Pythagorean expectation. Green Bay is the overwhelming leader in margin of victory and thus SRS. The team that’s played the toughest schedule with a chance of making the playoffs now is the New York Giants.
