The Irish defense will look markedly different in 2026 after an aggressive overhaul of its coaching staff. Rather than relying on fresh, untested talent, head coach Marcus Freeman tapped a group of veteran coordinators whose careers have intersected for years.
Chris Ash, now in his second year as coordinator for Notre Dame's defense, brings a track record of rapid turnarounds. He previously helped engineer a mid‑season surge that featured standout performances from holdovers Al Washington, Max Bullough and Mike Mickens.
Charlie Partridge joins as a position assistant with extensive experience at Wisconsin, South Florida and Florida Atlantic. His long‑standing relationship with Ash dates back to their days as co‑defensive coordinators at Wisconsin in 2011‑12, a bond that Freeman believes will translate into seamless communication on the field.
Brian Jean‑Mary, who served as South Florida’s defensive coordinator from 2017‑19, and Aaron Henry, the former Illinois defensive coordinator, round out the new unit. Both have navigated the pressures of Power Five programs and bring distinct perspectives on scheme and execution.
Testing New Information Flow
Spring practice served as a laboratory for the staff, allowing them to experiment with play‑calling hierarchies and real‑time adjustments. The team evaluated how quickly the new coordinators could disseminate concepts to players and among themselves, a factor that Freeman highlighted as critical for in‑game adaptability.
Early indicators are promising. Fans noticed a tangible lift in the defense’s performance during the second half of the Purdue game in Week 3, where the Irish forced three turnovers and limited the Boilermakers to a single field goal in that stretch.
Looking Ahead to the Season Opener
The revamped defensive staff will make its first public appearance when Notre Dame opens the 2026 campaign against Wisconsin in Green Bay. The matchup against the Badgers, a program with its own defensive pedigree, will serve as a litmus test for the synergy that Ash, Partridge, Jean‑Mary and Henry have cultivated during the offseason.
