When people think of the Kansas City Chiefs, Patrick Mahomes is the obvious headliner — the face of the franchise and the engine of the offense. But behind every elite quarterback is a supporting cast of stars who make greatness possible. So, who’s the most essential player on this Chiefs roster not named Mahomes?

Right now, the answer might be Trent McDuffie.

The third-year cornerback has quietly become one of the most important pieces of Steve Spagnuolo’s defense. After a breakout 2024 season, McDuffie earned a top-5 ranking in ESPN’s positional rankings, voted on by NFL coaches, scouts, and execs. His versatility — whether lining up outside, in the slot, or blitzing off the edge — makes him a true chess piece in a defense that thrives on confusion and pressure.

With the departure of L’Jarius Sneed, McDuffie’s role has grown even larger. He’s now the undisputed No. 1 cornerback, tasked with shutting down elite receivers week after week — and so far, he’s delivered. His instincts, footwork, and film study have made him a cornerstone of a defense that kept the Chiefs in games all season long.

While Mahomes will always be the heart of the team, McDuffie might just be its backbone. If the Chiefs are going to three-peat in 2025, they’ll need No. 22 to keep playing at an All-Pro level.
