If that’s the way you’re going to rank teams, you want to rank by resume, and that puts Washington ahead of Oregon and FSU in the top three.
That argument comes up all the time in ranking systems. Fans write in saying “my team beat that team-why aren’t they ranked higher?”. The answer is that they played more than one or two games.
It’s the performance in all the games that matters when people use the word “best”. Those are the predictive scales. The losses are data points, but they aren’t the only ones, Most of the metrics have Washington and Oregon neck and neck with each other, and some would have had a top four of Michigan, Washington, Oregon, and UGA.
You can either be predictive or you can measure merit.
