NFL insider names Denver Broncos as biggest threat to Chiefs’ AFC West dominance heading into 2025 season

Could the Chiefs’ AFC West reign finally be in jeopardy? According to NFL insider Albert Breer, the Denver Broncos aren’t just trending upward—they might be the team best positioned to knock off Patrick Mahomes and his teammates.

With fresh energy, tough practices, and a belief that’s turning heads, Denver is no longer just rebuilding—they're coming.

Denver Broncos’ grit and culture fuel their ascent

Albert Breer, writing for Sports Illustrated, singled out the Broncos as the top threat to Kansas City’s eight-year division dominance. Despite rising expectations for the Chargers and Raiders, it’s Sean Payton’s group in Denver that’s earned the most respect this offseason. “I think the Broncos might be emerging as the Chiefs’ top threat,” Breer wrote.The confidence isn’t just about roster upgrades—it’s about culture. “I saw the gassers they ran and the two-and-a-half-hour practice they scheduled,” Breer explained. “It’s hard for me to see a group that’s bought in the way this one is to backslide.” Denver’s 10-win 2024 season wasn’t a fluke—and the league is taking notice.

Sean Payton, now entering his third season with the Broncos, emphasized the team’s mentality and standards.

“I think they have a high standard of how they see themselves, and where we can be,” he was quoted as saying in the Denver Post. His coaching continuity and discipline are proving to be a catalyst for belief across the roster.

All eyes on Bo Nix and Denver’s defensive core

Key to Denver’s rise is the defense, led by Vance Joseph, which has become a physically imposing and mentally sharp unit. On offense, rookie QB Bo Nix is surrounded with talent and guidance, positioned to make a leap.

With Courtland Sutton, Marvin Mims Jr., and Javonte Williams, the pieces are quietly aligning.Meanwhile, Kansas City remains the division favorite—but cracks are forming. The offense, while potent, struggled with consistency last season, and offseason departures have tightened the margin. That leaves a narrow opening for a surging Denver team hungry for a power shift in the West.Also read: Patrick Mahomes' Super Bowl shame reignites debate — Is he still the NFL’s most feared quarterback?The NFL has already circled the Broncos-Chiefs rivalry with a Christmas Day rematch set at Arrowhead.
