Since this is being called a power ranking, I think I’d like this chart better if it only showed last 4 or 5 games. Teams at week 8 are becoming different than what they were in week 1. By week 18 week that week 2 team could be totally different.

I think that would take factors like team health and players learning new schemes into account better.

Anyone know if this is a piece of software being used for these charts? Maybe I’ll make my own.
