Boise and Fresno still have the highest strength of schedule because they have each played a very good team and no bad ones. So they’re still on top. Obviously they are going to play more games this season, so just hold on–it will shake itself out.
Also, strength of schedule for the better conferences will eventually rise as they get into conference play, while others will drop (for example, CUSA and MAC).
Again, I don’t use scores in this system. The ratings are based on wins, who you’ve beaten, and the strength of your conference (which will matter for playoff seeding).
