Serious college basketball numbers.
Zero paywall.

I'm Will Langfeldt, a business economics graduate from the University of Cincinnati. I got into basketball analytics during March Madness, trying to work out the why and the who behind every upset. Why does a 12-seed knock off a 5? Which teams are quietly better than their record says, and which ones are frauds waiting to get found out? Chasing those answers pulled me out of the box score and into efficiency ratings, and before long I was reading the analytics sites more closely than the standings. Eventually I wanted to run the numbers myself instead of trusting someone else's, so I spent a year learning the math and building this.

Everything on the site runs on a model I wrote in R. It re-rates all 365 teams each morning after the night's games, projects every spread, and grades every rotation player in the country. It's a one-person operation, which means when something breaks I fix it, and when you email an idea, I'm the one reading it.
