The Purdue Boilermakers has a top 10 defense this year. They're 6th in the nation in Kenpom's defensive rating. They lead the nation in opponent's effective field goal percentage allowing the 7th best 3 point shooting percentage against them and the second best percentage inside the arc.
The Boilers have done all this despite missing the reigning defensive player of the year Rapheal Davis for the last two games, including going into Pittsburgh to take on a very talented and tough Panthers team, and having three players in the rotation who are absolute negatives on the defensive end - the two true freshman, Ryan Cline and Caleb Swanigan, and the slow-footed Kendall Stephens.
