Rating Systems Challenge: National Championship Game Will Crown ESPN National Bracket or Lunardi RPI

This post is part of a series tracking the successes and failures of various NCAA Men's Basketball ranking systems and bracket models throughout the 2015 NCAA Tournament. Check out the full series.

The bad news is that Wisconsin's (1) upset of undefeated Kentucky (1) killed Sagarin's chances of winning the 2015 Rating Systems Challenge. The good news is that we're not done yet. Lunardi RPI, the only system to pick Duke (1) to win it all, can leapfrog to the top of the standings with a Blue Devils win tonight.

Should Wisconsin cut the nets tonight, it will be the first time since before WWII, and it will mean a victory for the ESPN National Bracket. No matter what, ten systems will have outperformed chalk this March (and April): an admirable performance.

Tune in tomorrow for the final results!
