The sample size is compiling. I noticed a poster keeps adding in past years. Its time consuming for me to get results that aren't as good as the black coach system. However, I don't have enough confidence to believe that a simple one variable method is predictive, but as you said it definitely is compelling as a valid input.

In past post I have actually commented on the race of coaches with the conclusion being it should be definitely be considered as a negative variable but I am surprised at the data and I never considered it to be among significant considerations. Maybe I am a nit, but unless I am overanalyzing a game well beyond just this one variable, I don't have the confidence to invest.
