The 2025 NFL season brings renewed intensity to the AFC West, particularly between two ambitious rivals—Denver and Los Angeles. The Broncos and Chargers are poised for two critical showdowns that could influence the playoff landscape and potentially shift the division hierarchy.

With both teams facing top-15 toughest schedules and high expectations, their matchups are more than just divisional clashes—they’re litmus tests of each squad’s resilience, growth, and playoff mettle.

Week 3: Denver at Los Angeles – A Test of Early Identity

The first of the two matchups arrives early—Week 3 at SoFi Stadium. By then, both teams will still be working out kinks, but the stakes are no less significant. It’s worth noting that Denver enters the season with momentum, fresh off ending an eight-year playoff drought in 2024.

Head coach Sean Payton, now in his third season, has built a defense-centered roster designed to impose its will on opponents. The Broncos will be coming off a pair of road games, including a trip to Indianapolis, which means fatigue and travel rhythm could play a role.

On the opposite sideline, Jim Harbaugh’s Chargers will have already tested their mettle in an international opener against Kansas City in Brazil and a Monday night game at the Raiders.

Whether those contests toughen them or wear them down remains to be seen. In either case, the early-season clash with Denver presents a crucial opportunity to assert divisional dominance—and could have an early impact on Los Angeles Chargers odds in a crowded AFC playoff picture.

Expect Denver’s defense to be the primary disruptor. They led the league in sacks last season and now boast additional firepower with safety Talanoa Hufanga and linebacker Dre Greenlaw joining Pat Surtain II and rookie Jahdae Barron. Their ability to pressure Justin Herbert—especially behind an offensive line still adjusting to travel-heavy demands—could set the tone.

For the Chargers, offensive rhythm will depend on how well Herbert adjusts to Denver’s disguised coverages and blitz-heavy fronts. L.A. must also lean on tempo and short-yardage efficiency to avoid letting the Broncos’ pass rush dictate the game.

Week 18: Chargers at Broncos – Potential Playoff Implications

The second meeting, set for Week 18 in Denver, has the makings of a playoff-deciding affair. While the NFL hasn’t confirmed a date, this late-season duel could determine wild card seeding or even the division crown—especially if Kansas City falters. The altitude, frigid weather, and high stakes could favor a Broncos team built for defensive showdowns.

Los Angeles, on the other hand, will be limping into Denver after a gauntlet of games: at Dallas, vs. Houston, and earlier trips to Philadelphia and Jacksonville. With the league’s highest travel mileage—37,086 miles—accumulated by season’s end, fatigue becomes a real concern.

Denver, meanwhile, will enter the final week after a home stretch that includes Green Bay and Jacksonville—games less grueling in comparison and offering opportunities to rest key players if postseason placement is secure.

The psychological edge may also favor Denver. The Chargers swept the Broncos last year, but both wins came during a soft schedule stretch. In 2025, with a stronger Broncos defense and an offense guided by Payton’s meticulous situational awareness, repeating that sweep won’t come easy. For bettors eyeing the best NFL game props this season on FanDuel, this Week 18 clash could offer some intriguing angles. Denver will likely deploy a more calculated attack, relying on sustained drives, clock control, and red zone efficiency to wear down an already taxed Chargers unit.

Quarterback Duel: Experience vs. Pressure

The Herbert vs. Broncos defense narrative will dominate both matchups. Since entering the league in 2020, Herbert has dazzled statistically but still struggles in high-leverage situations. That pattern showed during last season’s embarrassing wild card loss to Houston, where he posted one of his worst professional performances. He’s now under pressure to deliver—not just to restore fan confidence but for Harbaugh’s system to validate itself.

Meanwhile, Denver’s quarterback situation might not boast the same marquee appeal, but under Payton, efficiency and protection of the football remain paramount. Whether the Broncos continue with Jarrett Stidham or turn to a younger option, the offense will likely lean on its run game and defensive support. The goal? Don’t lose the game at quarterback; let the defense win it.

Denver’s ability to control the pace and minimize mistakes could exploit Los Angeles’s more aggressive, risk-prone defense. The Chargers love to pressure and bait turnovers, but that philosophy leaves them vulnerable to play-action and intermediate throws—precisely where Payton excels.

Linebacker Speed vs. Offensive Versatility

One subplot worth watching is how each team’s revamped linebacker unit performs. The Broncos, having added Dre Greenlaw in free agency, now pair sideline-to-sideline athleticism with veteran IQ. His presence will be pivotal in containing Chargers tight ends and spying Herbert on broken plays. Denver’s defensive interior also benefits from having more mobility, which may help against an L.A. backfield that loves to stretch runs wide and utilize motion to create confusion.

On the other side, the Chargers’ defense remains serviceable but unremarkable. With minimal offseason upgrades, their linebacking corps may be a weak spot, especially against Denver’s screen game and checkdowns. If Payton’s offense can force mismatches—particularly against slower coverage backers—the Broncos may be able to nickel-and-dime their way downfield with methodical efficiency.

Travel and Fatigue: Underrated Game-Changers

The Chargers’ travel schedule cannot be overstated. With the most miles logged in the league, the wear-and-tear across the season accumulates. By the time they reach Denver in Week 18, their legs may not have much left. Denver, by contrast, has clustered home games late in the year, allowing them to recharge just as postseason intensity peaks.

L.A.’s coaching staff has attempted to offset this challenge with creative logistics in the past—early departures, extended stays—but the effects of travel manifest in subtle ways: reduced reaction time, slower reads, minor injuries compounding. These physical disadvantages can make a huge difference against a Denver defense that thrives on punishing opponents who miss assignments or hesitate.

What’s at Stake

Beyond playoff implications, these matchups are tests of program stability. Payton’s third year with the Broncos is supposed to be the culmination of his rebuild—defensive identity, strategic precision, and meaningful football in December. Harbaugh’s second campaign with the Chargers, meanwhile, aims to prove last year wasn’t a mirage. He needs a quality record against playoff-caliber teams to shift the narrative and validate his approach.

Neither team can afford to stumble here. Denver needs to hold serve at home to keep pace with Kansas City. The Chargers must prove they can win meaningful road games late in the year—something they’ve struggled with historically. The winner of this two-game series may not just earn a playoff berth—they might avoid the Chiefs altogether in the first round.

These aren’t just rivalry games. They’re measuring sticks, microcosms of team philosophy, and previews of playoff intent. And when January nears, it’s often these matchups—full of subtle plays, mental errors, and halftime adjustments—that define who gets to play into February.
