Colorado Buffaloes rebuild defense with new leadership for 2025

The Colorado Buffaloes are focusing on rebuilding their defense for the 2025 season under new leadership. Defensive coordinator Robert Livingston is looking for senior defensive end Arden Walker to step up as a leader among the edge rushers. George Helow has been promoted to coach the defensive ends after Vincent Dancy left for Mississippi State. Helow aims to maintain the team's strong performance, as Colorado led the Big 12 in sacks last season with 39. Despite losing sack leader BJ Green to graduation, Helow is optimistic about the returning players and new recruits. The coaching staff, including Hall of Famer Warren Sapp, is focused on improving the team's performance and developing players.
