Breakdown and analysis of new Bears rookie Dillon Thieneman

The Chicago Bears selected Oregon safety Dillon Thieneman with the 25th overall pick in the 2026 NFL Draft.

Thieneman is a plug-and-play safety for the Bears on Day 1 following the departures of both starting safeties Kevin Byard and Jaquan Brisker in free agency. Thieneman is a versatile safety who thrived in coverage and as a run stopper. He has elite instincts and playmaking ability that should make him a difference maker in Dennis Allen's defense.

Breakdown

Teach-tape level tackler with impressive speed and football IQ. May need to bulk up at the NFL level but improved in both coverage and run defense in 2025. Alignment versatile prospect who can line up in the box, nickel or deep safety without cause for concern. Ideal vision and coverage acumen. Athleticism translated to field drills at the NFL combine. -- Ayrton Ostly

Dane Brugler's Scouting Report

A one-year starter at Oregon (and three-year starter overall), Thieneman was a hybrid safety in former defensive coordinator Tosh Lupoi’s scheme and wore a variety of hats (deep middle, robber, nickel etc.). A productive post safety at Purdue for two seasons, he transferred to Eugene for his junior season and earned a 2025 All-America nod for the Ducks, with both of his interceptions clinching victories late in a game (Penn State and Washington). He collected more than 300 combined tackles in three college seasons and averaged 7.9 tackles per start.

With his open-field athleticism, Thieneman has a lot to offer in the NFL because of his versatility making plays over the top in coverage or downhill versus the run. He shows impressive range and anticipation from the deep half of the field, as well as the intelligence to understand what opponents are trying to do. Although he doesn’t always play up to his testing numbers, he can guard both sidelines and sort through routes. He can clean up some things in the run game, too — he has a nose for the ball and doesn’t hesitate flying to the contact point.
