Just days after announcing his retirement from Montana, Bobby Hauck has accepted the position of defensive coordinator for the University of Illinois. Hauck, 61, cited a lack of enjoyment with the current state of college football as the reason for his initial departure, but has now decided to return to coaching, taking over the Illini defense.

Why it matters

Hauck's quick return to coaching after expressing dissatisfaction with the demands of being a head coach suggests a desire to focus on the technical aspects of the game and player development, rather than the administrative and external pressures of leading a program. His arrival signals a shift in defensive strategy for Illinois, as he brings his 3-3-5 scheme to the Big Ten.

The details

Hauck will replace Aaron Henry, who recently left to become co-defensive coordinator and defensive backs coach at Notre Dame. The new Illinois defensive coordinator will also be tasked with hiring a new defensive line coach, following Terrance Jamison's departure to the Buffalo Bills. Bret Bielema described Hauck's scheme as 'an exciting new style that has never been seen here at Illinois.' The defense will transition to a 3-3-5 formation, which Hauck developed while at San Diego State and refined during his time at Montana.
