Former Oregon Ducks safety Dillon Thieneman performed as one of the top safeties at the NFL Combine.
Throughout the broadcast on the NFL Network, former scout Daniel Jeremiah continued to mention that Thieneman stamped himself as a first round pick thanks to his performance at the NFL Combine. On Friday, Thieneman ran a 4.
35-second 40-yard dash, and he logged the second-highest vertical of all safeties with 41 inches.

With smooth footwork and strong hands, Thieneman looks the part as one of the best safeties of the draft. The top prospect at the position, former Ohio State Buckeye Caleb Downs, did not participate in any drills at the combine.Thieneman's 40-yard dash time ranks fourth-fastest among all safety prospects that ran at the combine. His vertical leap was the second-highest of all safeties that jumped.With three years to his college career, Thieneman spent two years in his home state of Indiana with the Purdue Boilermakers before transferring to Oregon for his junior year. In his sole year with the Ducks, Thieneman recorded 92 total tackles, 44 solo tackles, two interceptions, a sack, and five defended passes. Though those numbers fall short of his Purdue days, being around top talent at the Ducks can shave off a few tackles. Thieneman's strength with the Ducks is lining up is his versatility throughout the defense. Oregon utilized that factor throughout several of their packages with Thieneman having the ability to line up in nickel cornerback, outside linebacker, and free safety. His top games from the 2025-2026 season with Oregon includes his overtime interception against Penn State's quarterback Drew Allar that sealed Oregon's 30-24 victory during a White-out in Sept. and his seven total tackles and two passes defended against Wisconsin at Autzen Stadium in Oct., Thieneman was the No. 1 graded safety in the NCAA for the 2025-2026 season with a 91.0 rating. Thieneman surpasses fellow safeties like USC's Bishop Fitzgerald , Indiana's Devan Boykin , and Texas's Michael Taffee .

"The 6-foot, 205-pound Thieneman, who transferred from Purdue, is solid against the run and strong in coverage, and he covers ground quickly," Kiper continued. "I think he's going to run really well for the clock at pre-draft events. He's savvy, as well. Thieneman just needs to clean up his tackling. He gets sloppy there, as he's not a form tackler. I see him as a second- or third-rounder." In March, shortly after Thieneman transfered to Oregon, Ducks coach Dan Lanning pointed out Thieneman's dedication to being a student of the game. “He’s infatuated with the extra work. There's probably not a day that goes by that he’s not in the weight room, getting bonus work, doing extra rehab, getting extra film. His intelligence, all those things are really picking up, you know, establishing some standards for the DB group and how they're going to operate," Lanning said.Oregon defensive lineman Bear Alexander, left, and Oregon defensive back Dillon Thieneman bring down Washington quarterback Demond Williams Jr. as the Oregon Ducks take on the Washington Huskies on Nov. 29, 2025, at Husky Stadium in Seattle, Washington. | Ben Lonergan/The Register-Guard / USA TODAY NETWORK via Imagn ImagesWhen it comes to some drawbacks in Thieneman's performance, there's a few things NFL scouts are likely taking note of. First off is Thieneman's stature, which is a bit undersized for safeties at 6-0 feet and 205 pounds. He does need to improve on his tackling at the next level, with Thieneman shedding blocks occassionally and sometimes falling for misdirection from the offense. Inconsistent pursuit angles can come from Thieneman getting faked out by play action, but nothing that can't be worked on once attached to a team.

For the Bears, Thieneman would fill in for Kevin Byard, Jacquan Brisker, and C.J. Gardner-Johnson, all of which have contracts expiring within the year. Thieneman's ability to line up and down the defense can make him a natural fill-in for a variety of spots in the secondary. As for the Vikings, safety Harrison Smith is entering the later years of his playing career with a potential retirement decision on the way.A reporter for Oregon Ducks on SI, Ally Osborne is a born and raised Oregonian.
