The Denver Broncos have two-thirds of their defensive line set in stone, as former Tennessee Titans Pro Bowler Jurrell Casey and elite run-stuffer Mike Purcell are guaranteed starting spots.
Defensive end Shelby Harris, however, could be on the verge of losing the starting spot he was handed after Derek Wolfe left in free agency for the Baltimore Ravens.
In Vic Fangio's 3-4 defense, Harris gets a good deal of reps as a 3-tech lineman on the inside. It just so happens that Denver drafted two undersized but extremely explosive linemen in the last two years that offer more potential as pass rushers than Harris.
Former Ohio State star Dre'Mont Jones, a third-round pick in 2019, impressed in his limited reps, while 2020 third-rounder McTelvin Agim was incredibly impressive at the East-West Shrine Bowl and the Senior Bowl.
Harris might be a better run defender than either of these two, but Jones and Agim can both get after the quarterback, and their superior athleticism should given them an edge over Harris.
Harris was a nice find for the Broncos, but they have two extremely athletic linemen in Jones and Agim ready to rotate in Wolfe's old spot in the starting lineup, while Harris once again settles for a more rotational role.
