The Real Reason Bryan Cook Was a Backup Last Season – And His Strong Comeback This Year

Kansas City, MO – July 28, 2025

Last season, Kansas City Chiefs safety Bryan Cook found himself largely on the sidelines, a backup role that puzzled fans given his potential. In 2024, he appeared in 14 games, starting 11, with 54 tackles and one interception. Primarily a reserve behind Justin Reid, Cook also trailed Chamarri Conner in certain defensive setups, limiting his impact. His secondary role stemmed from Reid’s established leadership and Conner’s versatility, leaving Cook as a depth piece in a stout defense that reached Super Bowl LIX, only to fall 40-22 to the Philadelphia Eagles.

This year, however, Cook is seizing a golden opportunity. At 25, he’s poised for a breakout as the Chiefs’ secondary faces transitions. Justin Reid, now 31, is in the final year of his contract, and his age and recent wear (post-Super Bowl injury concerns) raise questions about longevity. The departure of defensive tackle Derrick Nnadi in the offseason has further thinned the roster, pushing Cook into the spotlight. Recent reports, including from Arrowhead Pride, highlight his impressive training camp performances, where he’s showcasing speed and instincts to fill the void left by departing veterans.

The Chiefs’ defense, exposed in Super Bowl LIX, needs depth, and Cook is stepping up. Defensive coordinator Steve Spagnuolo is reportedly impressed, with Cook logging significant reps and earning praise for his adaptability. If Reid’s performance dips or the team opts for a younger core, Cook’s path to a starting safety role looks promising. His 2024 stats, while modest, laid a foundation, and his current momentum suggests a potential leap.

With training camp in full swing, Cook’s chances are high. A strong preseason could cement him as a starter, especially if Reid’s $31.5 million deal with the Saints (post-2025 speculation) materializes. Fans are buzzing about his resurgence, seeing him as key to avenging last season’s loss. Can Cook transform from backup to backbone? Stay tuned as the season unfolds.
