Dillon Thieneman, S, Oregon
The Cowboys gave up the most points per game in the NFL last season (30.1) and the third-most yards per contest (377.0). They started to remake their secondary last season, and adding Thieneman, an active defender with positional and scheme versatility, would continue that process. Dallas specializes in two-high safety looks, and Thieneman is an excellent processor who can close on plays in a hurry. Dallas forced only 12 turnovers in 2025, and Thieneman has the ability to be a ball hawk while bringing physicality when stepping down against the run.
