Rating Systems Challenge: Wolfpack Deals Wild Blow to Twelve Brackets

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.

Short post today: here's how the various systems are performing after the first day of the second round. Vegas is beating everyone, but fully ten brackets are outperforming chalk and reside in the upper echelon of the ESPN Tournament Challenge.

Villanova's (1) loss to NC State (8) will hamper several systems going forward. Twelve brackets had Nova in the Final Four, six had the Wildcats representing their half of the bracket in the championship game.
