No. 9 — Senior DT Isaiah Thomas

The defensive front is the strength of defensive coordinator Alex Grinch’s much-improved 2021 Oklahoma defense. And a big part of the reason for that is senior defensive tackle Isaiah Thomas. Thomas played at both defensive tackle and defensive end for the Sooners last season and was credited with a team-high 8.5 sacks and 13 tackles for loss. He also recorded two fumble recoveries, two forced fumbles and eight quarterback hurries.

Thomas is a disruptive defensive force and a tough matchup for any offensive lineman. Pro Football Focus rated him as the No. 74 overall player in college football last season.
