Who became the Colts' new defensive coordinator before the 2012 season?

Greg Manusky became the Indianapolis Colts’ new defensive coordinator before the 2012 season.

The Colts hired Manusky on February 2, 2012, as part of a major coaching transition. He joined new head coach Chuck Pagano, who was also known for his defensive background, as Indianapolis prepared for the 2012 campaign. Manusky had already served as a defensive coordinator for the San Francisco 49ers and San Diego Chargers.

Manusky’s appointment came during a rebuilding period for Indianapolis. The team had moved on from the Peyton Manning era and was beginning a new chapter centered on rookie quarterback Andrew Luck. The defensive coordinator was responsible for organizing the unit’s schemes, game plans, and position coaches.

Manusky remained with the Colts for four seasons, working under Pagano, before being dismissed in January 2016. He later returned to the Washington organization as an outside linebackers coach and then defensive coordinator. The question refers specifically to the 2012 Colts season, so the answer is not Chuck Pagano; Pagano was the head coach, while Manusky held the defensive coordinator role.
