Terrorizing the Big 12: Jack Kelly’s Meteoric Rise at BYU
BYU linebacker Jack Kelly has spent the last year redefining what it means to be a modern defensive playmaker. After transferring from Weber State, Kelly quickly established himself as a dominant force in the Big 12, combining raw pass-rushing ability with an elite football IQ. As the 2026 NFL Draft nears, his performance during the 2025 season and his subsequent historic Pro Day have elevated him from a regional standout to a national defensive priority.
A Statistical Powerhouse in Provo
Kelly was the undisputed engine of the Cougars' defense in 2025. He tallied a team-high 10 sacks in just 12 games, the most by a BYU player in over a decade. Beyond his ability to find the quarterback, Kelly’s versatility was on full display as he recorded 55 total tackles, 13.5 tackles for loss, and two forced fumbles. His "superpower," according to defensive coordinator Jay Hill, is his closing speed, often used as a quarterback spy to shut down mobile signal-callers before they could reach the corner.
His impact extended beyond the stat sheet. As a team captain, Kelly’s leadership was vital during BYU's transition into the upper echelon of the Big 12. His ability to diagnose plays pre-snap allowed the Cougars to remain aggressive, knowing their middle linebacker could cover ground from sideline to sideline.
Historic Athleticism: The 9.83 RAS Score
If there were any doubts about how Kelly’s game would translate to the NFL, he silenced them at the 2026 NFL Combine and his following Pro Day in Provo. Kelly posted an unofficial Relative Athletic Score (RAS) of 9.83 out of 10.00, ranking him as the 57th most athletic linebacker out of over 3,200 prospects measured since 1987. His vertical jump of 37 inches and a 4.53-second 40-yard dash confirmed that his "game speed" was backed by elite explosive traits.
Versatility is the Key
NFL scouts are particularly intrigued by Kelly’s ability to play all three linebacker positions. In a league that increasingly demands linebackers who can stay on the field for three downs, Kelly’s background as a former safety and his refined coverage skills make him a rare commodity. Whether he is rushing off the edge or dropping into a zone to take away a tight end, Kelly has proven he is a matchup nightmare. With teams like the Pittsburgh Steelers reportedly showing high interest, the "Terror of the Big 12" is poised to bring his relentless motor to the professional ranks.
