With all the pre-draft speculation year in and year out, Chicago, unlike several teams, opted to simply let the board fall to them and were able to land a player that many didn’t think would be available when their pick came around.

Oregon defensive back Dillon Thieneman, right, brings down Texas Tech quarterback Behren Morton as the Oregon Ducks take on the Texas Tech Red Raiders in the Orange Bowl on Jan. 1, 2026, at Hard Rock Stadium in Miami, Florida.
After two seasons with Purdue, Thieneman transferred to Oregon ahead of the 2025 season and left his mark on both programs. Despite only playing two seasons at Purdue, Thieneman’s impact was felt from the very beginning, where he set school records both in interceptions and solo tackles as a true freshman.
During his lone season as a member of the Ducks, Thieneman had a season that elevated his draft stock, which ultimately led him to being a first round draft choice. In the 2025 season, Thieneman finished the year with 96 tackles and two interceptions, while also grading at a 91.0 on the PFF-grading scale for all defensive backs in college football.
Thieneman had the 11th-fastest 40-yard dash time of all players at this year’s NFL Scouting Combine back in February, with a 4.35 official time. That time was good enough to see him outrun multiple notable premier wide receivers currently in the NFL, including Justin Jefferson, A.J. Brown and Stefon Diggs.
Going back to his time at Purdue, Thieneman made history by being the first ever defensive player in Big Ten conference history to earn a weekly award five times in one year. Thieneman’s stellar play as a true freshman saw him win the Big Ten Freshman of the Week award five times, a conference record. He also set Purdue records with 74 tackles and six interceptions during his freshman year.
Thieneman was Mr. Football in state of Indiana during his high school days
Understandably, Thieneman went to Purdue after showcasing himself across the state of Indiana, where he would win Mr. Football while playing for Westfield High School in Indiana. Thieneman couldn’t get his team a championship, as they finished as runner-up twice but showcased his ability to be a pure clean tackler with over 250 tackles during his high school days. From Mr. Football in Indiana to Purdue, and then to Oregon, Thieneman is well experienced, well traveled, and highly talented dating back to when he was just getting his football career started.
