How Broncos Rebuilt Secondary Plans to Slow Down Patrick Mahomes
Denver's defense faces its ultimate test in Week 10. Here is how Vance Joseph and Pat Surtain II plan to disrupt Patrick Mahomes and the Chiefs.
It is the ultimate test in modern football. Standing across from Patrick Mahomes at Arrowhead Stadium is a daunting task for any defense, let alone one trying to establish a new identity. Yet, as the Denver Broncos head into their Week 10 AFC West showdown against the undefeated Kansas City Chiefs, there is a distinct sense of belief in Colorado. That confidence stems from a rebuilt secondary that has quietly transformed into one of the league’s most formidable units under head coach Sean Payton and defensive coordinator Vance Joseph.
Denver isn’t just hoping to survive Sunday’s matchup. They have designed a blueprint specifically to neutralize the game’s most dangerous signal-caller. It won’t be easy. Vance Joseph knows this. But the pieces are finally in place to give the Broncos a fighting chance.
The Surtain Island Factor
At the heart of Denver’s defensive resurgence is cornerback Patrick Surtain II. The All-Pro defender has put together a spectacular campaign, routinely erasing opponents’ top targets. Against a Chiefs receiving corps that has dealt with injuries throughout the season, Surtain’s role becomes even more critical. He is the anchor that allows everything else to function.
Joseph has shown a willingness to let Surtain travel with elite receivers, but against Kansas City, the challenge is different. With veteran DeAndre Hopkins now in the mix for the Chiefs, Surtain will likely see plenty of snaps against the newly acquired playmaker. By locking down one side of the field or taking away Mahomes’ preferred boundary target, Surtain allows Joseph to get creative with the rest of his coverage shells.
The Rise of Riley Moss and the Support Cast
But one lockdown corner does not make a secondary. In previous years, opponents could simply avoid Surtain and pick apart Denver’s defense elsewhere. That is no longer an easy option. Cornerback Riley Moss has emerged as a reliable, highly physical starter on the outside. His development has changed the mathematical equation for the Broncos defense.
In the slot, Ja’Quan McMillian provides the kind of feisty, instinctual play needed to disrupt Kansas City’s quick-passing game. McMillian’s ability to tackle in space and read Mahomes’ eyes in the short areas of the field will be vital, particularly when trying to limit tight end Travis Kelce on crucial third downs.
Behind them, safety Brandon Jones has brought veteran stability and range. Alongside P.J. Locke, Jones gives the Broncos the flexibility to disguise their coverages pre-snap. That is absolutely essential when facing a quarterback of Mahomes’ caliber.
Disguise, Delay, and Deceive
Vance Joseph’s scheme has evolved significantly this season. The Broncos are no longer playing passive zone coverages that allow quarterbacks to carve them up with small, easy completions. Instead, Denver has leaned into aggressive, high-variance football. They mix heavy press-man coverage with delayed safety blitzes and post-snap safety rotations.
You cannot give Mahomes the same picture twice. If he knows what the defense is doing before the snap, the play is already over. The goal for Denver is to make him hold the ball just a fraction of a second longer.
That extra fraction of a second is where Denver’s pass rush, led by Zach Allen and Nik Bonitto, comes into play. The secondary and the front seven must work in perfect harmony. If the coverage holds up for three seconds, the pass rush can get home. If the rush gets home, Mahomes is forced into the kind of rushed decisions that lead to turnovers.
Combating the Scramble Drill
Perhaps the biggest challenge when facing the Chiefs is not their designed plays, but what happens when those plays break down. Mahomes is the undisputed king of off-schedule playmaking. When he escapes the pocket, Chiefs receivers know exactly how to convert their routes into scramble-drill openings.
To counter this, Payton and Joseph have preached plaster coverage. When Mahomes breaks the pocket, Broncos defenders cannot watch the quarterback. They must stick to their assigned receivers like glue.
- Never look back at the quarterback while in coverage.
- Maintain physical contact within legal limits to prevent late separation.
- Trust the defensive line to finish the pursuit.
It takes immense discipline to chase receivers across the field for six or seven seconds. The Broncos have worked on this tirelessly in practice, knowing that a single lapse in concentration can result in a backbreaking big play.
The Game Plan: Complementary Football
Sean Payton knows that the best way to stop Patrick Mahomes is to keep him sitting on the bench. The Broncos offense, led by rookie quarterback Bo Nix, needs to sustain long drives to give the defense time to breathe. Time of possession will be a massive factor on Sunday.
But when the defense is on the field, they must force the Chiefs into long, methodical drives rather than quick-strike touchdowns. If Denver can eliminate the explosive plays that have defined the Chiefs’ offense for years, they force Mahomes to execute 10- to 12-play drives without making a single mistake. In a noisy, hostile environment like Arrowhead, that is a recipe for success.
It is a massive hurdle. But this isn’t the same Broncos team that struggled defensively a year ago. This group is faster, more aggressive, and far more confident. On Sunday, the football world will find out if Denver’s defensive overhaul is truly ready for the ultimate test.
