It is my guess that it would still be the case that only a small proportion of the seasons with different actual and Pythagorean pennant winners would differ by one standard deviation or more in their records and that seasons with differences of two standard deviations or more would be extremely rare (perhaps just the 1987 American League). A few notable differences in the history of actual and Pythagorean pennant winners are noted here. It is possible to compare individual players' speed to their offensive and defensive performance, and doing so would be a much larger correlation. If you look at the recent histories of each team, turnovers happen to be somewhat predictable.

When predicting season wins, we also must factor in some of the less quantifiable information such as the clutch performances from quarterbacks like Tom Brady and Patrick Mahomes along with the anti-clutch performances of Matt Ryan and Kirk Cousins.

I encourage people to specialize in a conference or division that will help give them the greatest edge in their sports wagers. All rights reserved. Think of points scored as (a), and points allowed as (b) where (c) is a function of the (a and b) linear equation and we just want to know what the relationship is between a^2/c^2 (c^2 is a^2 + b^2)to get a percentage of wins multiplied by the total games. And since 2012, there has been a wild-card game before the two tiers of playoffs to determine pennant winners. Wikipedia - Pythagorean Expectation - An entry on the concept of Pythagorean .

I myself find that using the constant exponent of 2.37 doesnt deviate significantly enough from Moreys exponent model with respect to the actual randomness in the sport of football itself. The highest correlated pitch velocity with wins was fastballs coming in at 0.099, which is not even moderately correlated. November 1st MLB Play.
