Bryan Cook Named Bengals’ ‘X Factor’ Ahead of Dexter Lawrence

The Cincinnati Bengals spent this offseason constructing one of the most formidable defensive units in the NFL entering the 2026 season. On paper, this is a unit capable of matching up with the best offenses in the AFC.

While the Dexter Lawrence trade has dominated headlines the most, another blockbuster move may prove just as important once the season begins.

The Bengals signed Bryan Cook to a three-year, $40.25 million contract in March, making him the highest-paid safety in franchise history. The signing addressed a problem that quietly crippled Cincinnati’s defense for two straight seasons: the instability beside Jordan Battle at safety.

For the last two years, that role belonged to Geno Stone and it wasn’t the best of pairings. According to PFF, Stone missed a team-high 23 tackles in 2025.

Cook was acquired by the Bengals to fill that void and Brentley Weissman of The Draft Network believes it’s one of the most significant moves the front office made this offseason. 

Appearing on “The Mina Kimes Show,” Weissman identified Cook as Cincinnati’s true X-factor entering 2026.

“Obviously the low hanging fruit was Dexter Lawrence but I decided to go with another acquisition they made this offseason, which is Bryan Cook, coming from Kansas City,” Weissman said. “For me, I love Bryan Cook as a player, but it’s also more about who he is replacing. Geno Stone was awful, truly terrible. The Bengals allowed the most explosive 20-plus yard plays on defense in the NFL. A lot of those plays were long run plays and it was directly because of Geno Stone’s missed tackles… Bryan Cook coming in, well, he is not Kyle Hamilton or anything like that. But what he provides this defense is a good, reliable player in both coverage and run support.”

Cook arrives in Cincinnati with a résumé that supports Weissman’s take. The former second-round pick spent four seasons with the Kansas City Chiefs, winning two Super Bowls while developing into one of the league’s best safeties within Steve Spagnuolo’s defensive system.

In 2025, Cook recorded a career-high 85 tackles and six pass deflections while earning an 83.5 PFF overall grade, the fourth-best mark among NFL safeties. His 83.2 coverage grade ranked sixth at the position, and his five missed tackles placed him among the league’s most dependable open-field defenders.

The Bengals will get their first look at the rebuilt defense on Sept. 13 when they host the Tampa Bay Buccaneers at Paycor Stadium. The unit that ranked as one of the worst defenses in football last season now has a totally different identity and Cook is expected to play a huge role in their success.
