As the Illinois football team faces several key personnel losses on both offense and defense, one player who will be counted on to step up is senior safety Matthew Bailey. With star linebacker Gabe Jacas leaving for the NFL, Bailey is expected to be the new leader of the Illini defense under first-year coordinator Bobby Hauck.

Why it matters

Bailey's experience and versatility will be crucial for an Illinois defense that is undergoing a significant transition. The Illini are switching to a 3-3-5 scheme, and Bailey's ability to play multiple roles in the secondary could allow the new coordinator to get creative in generating pressure and making plays.

The details

Despite missing the end of last season due to a shoulder injury, Bailey still led the Illini defense with 76 tackles, including four for loss, and added two forced fumbles, a recovery, and two pass breakups. His tackling and playmaking ability will be counted on again in 2026, but Hauck's five-DB base defense could turn Bailey loose as more of a blitz threat and ball-hawking safety. The Illini will need Bailey to step up with the departure of Jacas and the entire starting defensive line.

  • Bailey missed the Music City Bowl last season with a shoulder injury.
  • Illinois head coach Bret Bielema praised Bailey's potential and leadership back in January 2026.
