We are diving into some fantasy football content this offseason as we look to bring in all sorts of football fans to Bucs Wire. While offensive players often dominate fantasy football discussions, IDP leagues continue to grow in popularity, offering another way for fans to enjoy the game.
We will start with some rookie profiles and how they fit into the landscape of the teams that drafted them. Next up is Kansas City Chiefs edge defender R. Mason Thomas.
Thomas enters the NFL after four seasons at Oklahoma, where he developed into one of the more intriguing pass-rush prospects in the 2026 rookie class. His final season was his most efficient, producing 28 pressures, six sacks and a 90.4 pass-rush grade from PFF while continuing to showcase the burst and bend that made him a disruptive presence off the edge.

Reason to Believe in R. Mason Thomas in 2026: Pass-rush upside creates opportunity
Kansas City drafted Thomas because of traits that are difficult to teach. His explosive first step immediately puts offensive tackles under pressure, and he has the flexibility to corner tightly around the edge while maintaining balance through contact. Those tools helped him generate 63 pressures and 17 sacks during his final three seasons at Oklahoma despite never being a full-time volume player.
The fit with the Chiefs is also appealing. Chris Jones remains one of the NFL’s premier interior disruptors, while George Karlaftis continues to command attention as the team’s top edge defender. That combination could create favorable one-on-one opportunities for Thomas whenever he sees the field.
His production late in games is another reason for optimism. Thomas consistently found ways to affect quarterbacks in critical situations, displaying the motor and competitive mentality that coaches value in rotational pass rushers. If he earns trust quickly, his role could grow throughout the season.
2026 Outlook
Thomas enters the season as a developmental edge defender with upside in deeper IDP formats. He is unlikely to open the year with a full-time workload, but Kansas City’s defensive line rotation should provide opportunities for him to contribute as a designated pass rusher.
The biggest questions involve his size and run defense. At 249 pounds, he can struggle to anchor against power rushing attacks and larger offensive linemen. That may limit his early-down usage until he develops more strength and consistency at the point of attack.
For fantasy managers, Thomas is primarily a watch-list player entering 2026. However, his pass-rush talent gives him more upside than many rookie rotational edge defenders, making him a worthwhile stash in deeper IDP leagues if his snap count begins trending upward during the season.
