They finally acknowledged Buddy Taylor's discovery of this stat. That said, beware of next year as these things always evolve.

If you read through their website they say that their only loss was San Diego last year at New England. I don't understand how they count that as a loss because San Diego covered the spread. If they are just saying that they have picked the winner to each game, then they have not covered each game. Just seems contradictory. Maybe someone else could explain this to me.
Which game did it predict the winner incorrectly last year?
someone just posted in another thread that the team that wins the conference championship over the last 40 years is undefeated against the spread so it should be useful for that.
