Admittedly, kenpom is the leader in college basketball metrics. It is not, however, the end-all-be-all.
On kenpom.com: "The first thing you should know about this system is that it is designed to be purely predictive. If you’re looking for a system that rates teams on how 'good' their season has been, you’ve come to the wrong place."
I recently tried to express interest in how well kenpom does with its ratings, especially how well it takes strength-of-schedule into account. Some of you disapproved.
So, let's take a look at how well kenpom has done with Michigan this season. Comparing the predictions that mgoblog has published and comparing them to actual results, kenpom has accurately predicted the winning team in Michigan's games 65.2% of the time, with an average error of 8.4 points in those contests. During B1G play, the kenpom accuracy in Michigan games has dropped to 60% with an error of 9.8 points.
