The Colts have announced their finalized coaching staff for the 2025 NFL season, per Mike Chappell of FOX59. No changes were necessary on the offensive or special teams sides of Shane Steichen‘s coaching staff, but with the arrival of new defensive coordinator Lou Anarumo from Cincinnati, there were a couple changes to the defensive staff. 
To preface, Anarumo didn’t actually make very many updates to the defensive staff that had coached under former coordinator Gus Bradley in 2024. The newcomer made the decisions to retain defensive line coach Charlie Partridge, senior assistant/defensive line coach Matt Raich, assistant linebackers coach Cato June, defensive quality control coach Brent Jackson, defensive assistant Brent Stockstill, and both Tony Dungy Diversity Coaching Fellows Diego Ortiz and Kalon Humphries.
The changes that were made to the staff were already reported or mentioned, as well. We noted already that James Bettcher landed as linebackers coach after defensive coordinator gigs in Arizona and New York, and we also reported that Chris Hewitt departed Baltimore to accept a role as pass game coordinator/secondary coach under Anarumo.
The other new hire was someone we had noted that Indianapolis had interest in. About a week ago, we relayed that the Colts were targeting veteran defensive backs coach Jerome Henderson for a role on their staff, noting that with Hewitt as secondary coach, Henderson’s role may be unclear. Regardless of Hewitt’s title, Henderson was brought on to serve as defensive backs coach, per Matt Zenitz of CBS Sports. Henderson has served as defensive backs coach for the Jets (2008), Browns (2009-11), Cowboys (2012-15), and Giants (2020-24) with additional years as a defensive passing game coordinator for the Falcons (2016-19) and the Giants last year.
