Jack Kelly: The BYU Chaos Agent Set to Disrupt NFL Backfields
Jack Kelly: The BYU Chaos Agent Set to Disrupt NFL Backfields
When the BYU Cougars transitioned to the Big 12, they needed an infusion of athleticism and aggression on the defensive side of the ball. They found exactly that in Jack Kelly. As NFL teams buzz about the linebacker’s transition to the professional ranks, Kelly has established himself as one of the most productive “chaos agents” in the country. With 10 sacks in the 2025 season, Kelly became the first BYU player since Bronson Kaufusi to reach double-digit sacks in a single year, earning First-Team All-Big 12 honors in the process.
Kelly is not your traditional off-ball linebacker. At 6’2” and 242 pounds, he plays with an “unhinged motor” that allows him to excel as both a gap invader and a situational edge rusher. In 2025, he produced a staggering 30.2% pressure rate on pass-rush reps, a number that has defensive coordinators at the next level salivating. His versatility was the cornerstone of a BYU defense that surprised critics by finishing the season with ten wins and a bowl victory over Georgia Tech.
BYU’s Resurgence: A Ten-Win Season
The 2025 BYU Cougars finished 10-3, anchored by a defense that thrived on Kelly’s ability to create negative plays. The season’s highlights included a thrilling victory over rival Utah and a dominant performance against UCF to close out the regular season. The team’s final act was a convincing win in the Pop-Tarts Bowl, where Kelly once again proved to be the most disruptive player on the field despite playing through a lingering shoulder injury for much of the autumn.
BYU 2025 Defensive Stats:
- Sack Leader: Jack Kelly (10.0 sacks)
- Tackle for Loss Leader: Jack Kelly (13.5 TFL)
- Tackle Leader: Faletau Satuala (83 tackles)
- Last Game Result: 2025 Pop-Tarts Bowl Win vs. Georgia Tech.
Draft Projection: Special Teams Demon and Sub-Package Weapon
As the April 23 draft kickoff nears, Kelly is widely projected as a fifth-round pick, though his stock has risen following a stellar combine performance where he posted a 9.83 RAS (Relative Athletic Score). While concerns remain regarding his 18.5% missed tackle rate and average fluidity in deep zone coverage, his floor as a special teams standout is incredibly high. Teams like the Indianapolis Colts and Pittsburgh Steelers have reportedly hosted Kelly for pre-draft visits, viewing him as a Jamie Collins-esque project who can contribute immediately on third downs and kick coverage.
