The Colorado Buffaloes' defense virtually reset after a disappointing 2025 season, where they ranked among the worst in the Big 12, allowing 30.5 points and 425.7 yards per game. The arrival of new defensive coordinator Chris Marve and 29 transfers aims to transform the defensive unit into a more aggressive and competitive group. With only eight returning players on a roster of 44, the Buffs are looking to build a defense that can perform at a higher level and improve on last year's metrics.

By the Numbers
  • Buffs ranked 13th in the Big 12 in points allowed (30.5 per game).
  • Ranked 135th out of 136 FBS teams in rushing defense (222.5 yards allowed per game).
State of Play
  • New defensive coordinator Chris Marve is instilling a philosophy of being "violent and aggressive."
  • Only eight players return from last season, with 29 new transfers enhancing the roster.
  • Inside linebacker trio of Lampron, Lefau, and Martinez is projected to be a major strength.
What's Next

The Buffaloes aim to implement aggressive strategies in the upcoming season, with expectations to improve their rankings significantly. As the team solidifies its new roster and tactics, performance in the early games will be critical to establishing a successful defensive identity.

Bottom Line

The Colorado Buffaloes have taken bold steps to rebuild a struggling defense, changing nearly the entire roster and hiring a new coordinator. Success in the coming season hinges on the quick adaptation and effective execution of their new aggressive style.
