Dillon Thieneman is a safety and 2026 NFL Draft prospect who finished his collegiate career at Oregon after two seasons at Purdue. A native of Westfield, Indiana, Thieneman was a three-star recruit in the 2023 class who won the Indiana Football Coaches Association Mr. Football award at defensive back before signing with the Boilermakers, following in the footsteps of brothers Jake and Brennan, who also played safety at Purdue. He made a historic immediate impact, recording 106 tackles, six interceptions and two forced fumbles as a true freshman in 2023 to earn Big Ten Freshman of the Year and third-team All-American honors, one of the most decorated debut seasons by a defensive back in Purdue program history. He followed with 104 tackles in 2024 as a sophomore, leading all Big Ten defensive backs in that category. After Purdue's program struggled and he sought a higher stage, Thieneman entered the transfer portal and joined Oregon, where he continued to produce in 2025 with 96 tackles, two interceptions, 3.5 tackles for loss and five passes defended while earning first-team All-Big Ten and first-team All-American recognition as part of the Ducks' CFP run. His three-year career totals include over 300 tackles and eight interceptions across 39 games.
Measured at 6-foot and 207 pounds with a 4.35-second 40-yard dash, Thieneman is one of the top safety prospects in the 2026 class and one of the most productive defensive backs in recent college football memory. His instincts as a single-high free safety are exceptional, with the ability to diagnose run-pass keys rapidly, patrol the deep middle with range and arrive on the ball before it reaches its intended target. He played every safety alignment at both Purdue and Oregon including deep safety, robber, box and slot, demonstrating the versatility that modern NFL defenses require at the position. He processed quarterbacks and route concepts efficiently in two different college systems, and his extraordinary productivity at Purdue as a freshman reflected the kind of innate defensive feel that is typically not teachable. The concerns center on his lateral agility in man coverage against quick-twitch slot receivers and some stiffness in his hips that limits him in isolated man assignments. His best NFL fit is in zone-heavy, two-high structures where his range, processing and tackling can be maximized rather than schemes that require extensive man-coverage responsibilities. Most evaluations project him as a late first-round or early second-round pick with legitimate starter upside as a versatile, high-football-IQ safety.
