Cornerback Boo Carter, a transfer from Tennessee, has caught the attention of Colorado's new defensive coordinator Chris Marve during spring practices. Marve praised Carter's love for the game and willingness to do whatever is asked of him. Carter brings great speed and playmaking ability to the Buffaloes' secondary, and could be used in a variety of roles to help improve Colorado's pass defense, which struggled at times last season.

Why it matters

Colorado's pass defense was solid but not dominant in 2025, ranking 41st nationally in passing yards allowed per game. The Buffaloes also had just 6 interceptions, tied for 76th in the country. With new defensive coordinator Chris Marve looking to maximize the talent in the secondary, players like Boo Carter could be the key to improving Colorado's pass defense and making a run at the Big 12 title.

The details

Carter recorded 25 tackles, 4.5 tackles for loss, 1 sack, 3 pass breakups, and 3 forced fumbles during his 2025 campaign at Tennessee. His speed and versatility give Marve options to use him as a cornerback, safety, or in other defensive back roles to limit opposing passing attacks. Marve praised Carter's commitment and willingness to do whatever is asked of him, which has impressed the coaching staff during spring practices.

  • Carter transferred from Tennessee to Colorado for the 2026 season.
  • Colorado's spring game is scheduled for this Saturday.
