Subscribers of KenPom, an analytics website, voted UConn #1 through an algorithm/process that is designed to be more accurate and have less groupthink. Humans are good at comparing two things, but not as good at ranking multiple similar complex things in order. But if you get enough comparisons of two things (thousands), you can turn those individual matchups into an actual ranked list using math. And yeah, UConn #1 from smart basketball fans who pay money to look at analytics. KenPom uses this "H.U.M.A.N" ranking as a small piece of his overall algorithm, which will be released soon.
Evan Miya also released his analytical model. It's pretty good in general and unfortunately had UConn 9th, which is better than some other models like Torvik which has us in the teens.
