5 takeaways from the Kansas City Chiefs' 2025 preseason

The Kansas City Chiefs failed to win a game in the NFL's 2025 preseason and will look ahead to their Week 1 matchup against the Los Angeles Chargers in Sao Paulo, Brazil, on September 5.

While their losses in the preseason won't affect Kansas City's quest to earn a fourth-consecutive Super Bowl berth, the inauspicious start of the Chiefs' 2025 campaign revealed a few strengths and flaws that may bear themselves out during the regular season.

Assessing the performance of any team in the preseason is an imperfect science, but with three games against live competition complete and Week 1 officially on the horizon, here are our five takeaways from Kansas City's August exhibitions:

Patrick Mahomes, Chiefs' first-team offense looked ready to compete

In limited action during Kansas City's first and third preseason games, Patrick Mahomes threw two touchdown passes and looked like he was locked in on every snap he played. For that matter, the Chiefs' whole first-team offense — including Kansas City's new-look offensive line and receiving corps — appeared to be in great shape and ready to compete at a high level.

Chiefs' run defense faltered in the preseason

Kansas City has had a stout run defense in recent years, but it struggled to stop the ground game in the preseason. In three exhibition matchups, the Chiefs allowed a total of 522 net rushing yards. Should Kansas City continue to flounder against opposing rushing attacks to this degree in the regular season, the Chiefs will struggle to win close games consistently.

Hopefully, the lax run defense was a product of backups playing the majority of snaps for Kansas City's defense, and not a sign of ineptitude to come.

Andy Reid has some difficult decisions to make about Kansas City's receiving corps

The Chiefs saw several up-and-coming wideouts excel during training camp and the preseason. Veteran speedster Tyquan Thornton was among Kansas City's most productive receivers and seemed to have chemistry with Patrick Mahomes, in particular.

Others who played well were Jason Brownlee, Jimmy Holiday, and injured rookie Jalen Royals. The only true "locks" to make the Chiefs' 53-man roster are Xavier Worthy, Rashee Rice, and Marquise 'Hollywood' Brown.

The uncertainty surrounding Rice's eventual suspension may force the Chiefs' front office to get creative in its approach to the receiver position.

Chiefs' pass-rush was relatively quiet; has already dealt with injuries

Kansas City only tallied three sacks across its three preseason contests, one of which was recorded by veteran defensive lineman Janarius Robinson, who is currently on the Chiefs' injured reserve list with former first-round pick Felix Anudike-Uzomah. Chris Jones and Charles Omenihu combined for a sack against the Chicago Bears in Kansas City's preseason finale, but the Chiefs' pass-rush was mostly held at bay by opposing offensive lines.

Between the lack of production and injuries, the outlook for Kansas City's defensive line doesn't look great on paper. Fans will have to hope that the Chiefs' first-stringers can get off to a hot start against the Chargers in Week 1.

Utter collapse in preseason finale, 0-3 preseason record does not bode well for Kansas City

I'm probably wrong about this point, but in the aftermath of the Chiefs' last-second loss to the Bears, it nonetheless feels appropriate to mention.

Kansas City has been a well-oiled (regular season) game-winning machine in recent years, and was completely outdueled by a first-year head coach's third-stringers in last night's contest. The Chiefs held a lead from their first drive in the first quarter until Chicago's final possession in the fourth quarter, which saw Tyson Bagent slice and dice Kansas City's secondary to run a perfectly executed two-minute drill while down five points.

Preseason games are meaningless, but an utter collapse is never a good sign, even in a no-stakes environment. The Chiefs' losses to the Arizona Cardinals and Seattle Seahawks weren't pretty either, and blunders like the one fans witnessed on Friday night have been rare in the Andy Reid era.

Week 1 will be an excellent test of whether Kansas City's preseason struggles were indicative of a broader dysfunction or simply the result of inexperience among the Chiefs' second and third-string players.
