Schedule Strengths (2 of 3): Historical Schedule Strengths
By Caleb Sykes
In my most recent post, I investigated what would be the best generally applicable “Strength of Schedule” metric. I settled on something I’m calling “Average Rank Difference” which is just the sum of all opponent “ranks” minus the sum of all partner “ranks” plus a few adjustments to normalize between events. Now, what we decide to use for ranks could be anything, but it has to be something you have available before the event starts, so you can’t use each team’s seeding rank at the end of the event you are analyzing for example. Possible options could be: Team number, previous events/years winning record, previous district points, previous event ranks, Elo, OPR, etc… For the analysis in this article, I’m going to be using Elo since I have it readily available, and I think it’s generally better suited for questions like this than any of the alternatives.
