Biography: Three-year starter awarded All-American and all-Conference honors the past two seasons. Named Big Ten Defensive Player of the Year in 2010 after totaling 70/26/12.5. Junior numbers included 66/18.5/13.

Positives: "Intense defender who has been one of most prolific pass rushers in the nation the past two years. Displays outstanding first-step quickness, plays with suddenness, and viciously attacks ball carriers. Fast off the edge, gets his hands up, and effectively uses them to protect himself. Plays with good balance, rarely off his feet, and can flatten off the edge and pursue the action from the back side. Plays with terrific pad level, quickly changes direction, and is fluid moving in every area of the field. Relentless in pursuit of the action, displays an explosive burst of speed, and is constantly around the action. High-character prospect known for his work ethic."

Negatives: "Lacks bulk, neutralized at the point of attack, and struggles shedding blocks. Tends to take wide angles around blockers instead of meeting them head on. Primarily used up the field at Purdue and rarely asked to drop off the line of scrimmage."

Analysis: "Kerrigan has been an exceptional defensive player who has taken over games the past two seasons. He possesses all the skills to be a one-gap defensive end at the next level, and though he lacks the great upside, Kerrigan comes with minimal risk."
