Massey’s approach has limited relevance in early season, unless you believe that past season final ranking is a good indicator of current season performance. It needs more “networked” games to be effective for the current season. I did not look at it last week, but I’d bet it had UW beating Cal quite handily, as it was effectively comparing the performance of last years teams.
That said, it’s better than a bunch of AP asshats guessing about games they didn’t watch.
