Many of you have asked me to include a strength of schedule component (SOS) into my power rankings. For years, there was not a quick way for me to do that, so I punted. The rankings were still valuable, but I always have looked for a chance to incorporate what should be the final piece of the rankings puzzle. Thanks to TeamRankings.com, I finally have what I need.
The basic rankings calculation will remain as it was before, but I will now add in a team’s SOS into their score. A negative SOS will drag down their team strength. A positive SOS will push it upward. As it should be. I played a bit with just how much of a factor SOS should be, and am happy with the result. And not just because Seattle jumped five spots!
A team like San Diego has had the toughest schedule in football through three weeks, and climbed #11 to #5. That feels far more appropriate given what they have accomplished.
I do not have an easy way to go back and re-calculate past power rankings with SOS factored in, so we start fresh. That is okay. We have done it before. Never let history get in the way of innovation.
I have included this week’s rankings using the old formula for comparison. I think you will agree the rankings above are a better product.
