The Kansas City Chiefs put up one of their most potent offensive showings in recent memory in Week 5, yet still walked away with a loss against the Jacksonville Jaguars.
According to exclusive PFSN data, the Chiefs posted an 87.1 Offense Impact (OFFi) grade, their third-highest mark in a defeat since 2000. Only their 2002 loss to the Seattle Seahawks (89.6) and a 2021 loss to the Baltimore Ravens (88.6) rate higher. The numbers tell a story of a team that, despite moving the ball efficiently and generating opportunities, failed to convert those advantages into a win.
How Did Patrick Mahomes Play Well and Still Lose?
Patrick Mahomes delivered his sharpest game of 2025 in key situational metrics, recording a season-high 78.5 QB Impact (QBi) score. His performance under pressure was especially impressive; he averaged 0.67 Expected Points Added (EPA) per dropback when Jacksonville brought heat, his best mark of the season in that situation. This kind of high-efficiency passing against pressure usually fuels victories for Kansas City, as drives are extended and turnover risks are minimized.
The problem came when the Jaguars didn’t pressure Mahomes. In those clean-pocket situations, his numbers collapsed. He posted -0.18 EPA per dropback, his fourth-worst figure without pressure since 2019, when TruMedia began tracking such splits.
This left Kansas City in a paradox: Mahomes looked elite when the defense blitzed or collapsed the pocket, but he was inefficient when the play developed as designed. Whether it was poor timing with receivers, defensive disguises from Jacksonville, or missed windows, the lack of clean-pocket success cost the Chiefs valuable possessions.
This dynamic isn’t an isolated issue. PFSN grading shows Mahomes has now gone six straight games with a C-level or lower QB Impact grade, dating back to last season’s Super Bowl. Over his last 16 games, he’s earned a B or better just once (in the AFC Championship win over the Buffalo Bills). For a player whose career averages have rested comfortably in the A-range during peak seasons, this sustained downturn in evaluative grading raises questions.
The offensive output in Jacksonville wasn’t hollow. Kansas City moved the ball enough to warrant an 87.1 OFFi grade, but critical breakdowns kept them from capitalizing. Missed third-down opportunities, a pair of stalled red zone trips, and one poorly timed turnover swung possession and momentum. The data reflects efficiency in spurts rather than consistent execution, a hallmark of recent Chiefs losses despite big individual stat lines.
An OFFi grade in the upper 80s is rare in losses because it typically indicates efficient plays, high yards per attempt, and strong situational success. Historically, league teams winning with such offensive grades hover above 80% in win probability. For Kansas City, hitting 87.1 and losing shows a unique imbalance: the execution in certain high-leverage situations fell short compared to total play-by-play efficiency.
Mahomes’ clean-pocket troubles against Jacksonville are worth monitoring. In his peak seasons, he excelled from clean platforms with an EPA per dropback firmly in the positive range, often above +0.30. Struggling in those scenarios means opponents don’t have to overwhelm him with pressure to disrupt his rhythm; disguising coverage and forcing hesitation appear to be enough.
Combine that with a stretch of middling QBi grades, and Kansas City’s offensive identity starts to look more volatile than in past championship runs. The Chiefs can still score in bunches, but this game underlines that their margin for error has narrowed offensively.
