Mahomes Under Pressure: How the Eagles’ Defensive Line Exposed the Chiefs’ Weaknesses in Super Bowl LIX
The Kansas City Chiefs entered Super Bowl LIX, played on February 9, 2025, at the Caesars Superdome in New Orleans, with history on their minds. A victory against the Philadelphia Eagles would crown them as the first NFL team to win three consecutive Super Bowls. However, the Eagles, led by a dominant defensive performance, had other plans. In a rematch of Super Bowl LVII, Philadelphia soared to a 40-22 victory, exposing vulnerabilities in the Chiefs’ offensive line and putting immense pressure on Patrick Mahomes.
A Defensive Masterclass
The Eagles’ defensive coordinator, Vic Fangio, orchestrated a defensive scheme that flustered Mahomes throughout the game. Philadelphia’s defensive line, featuring Jalen Carter, Milton Williams, Josh Sweat, and Nolan Smith, consistently pressured Mahomes, sacking him a career-high six times. What made this performance even more remarkable was that the Eagles achieved this without blitzing, relying solely on their front four to generate pressure. According to Next Gen Stats, the Eagles did not blitz once across 42 dropbacks, generating 16 pressures and sacking Mahomes six times. This allowed the Eagles to allocate more players in coverage, further stifling the Chiefs’ passing attack.
Chris Simms of NFL on NBC noted that the Eagles’ defensive line’s dominance was reminiscent of the pressure Mahomes faced in Super Bowl LV against the Tampa Bay Buccaneers. The Eagles’ ability to generate pressure with just four rushers forced Mahomes to make quick decisions, often leading to errant throws and turnovers.
Mahomes Under Siege
Patrick Mahomes, a three-time Super Bowl MVP, struggled mightily against the Eagles’ relentless pressure. He completed 21 of 32 passes for 257 yards, with three touchdowns and two interceptions. However, his passer rating of 95.4 doesn’t fully reflect the difficulties he faced. Mahomes was constantly under duress, and his discomfort in the pocket was evident.
DAZN reported that Mahomes had a passer rating of just 10.7 in the first half, the third-worst first-half performance by any quarterback that season. His favorite target, Travis Kelce, was also held in check, recording zero receptions in the first half for the first time in his playoff career.
One of Mahomes’ interceptions was a costly pick-six to Eagles’ rookie cornerback Cooper DeJean, who intercepted a pass and returned it 38 yards for a touchdown. This play exemplified the Eagles’ ability to capitalize on Mahomes’ mistakes and turn them into scoring opportunities.
Offensive Line Woes
The Chiefs’ offensive line, which had been a concern throughout the season, struggled to contain the Eagles’ pass rush. The Eagles’ defensive front consistently won their one-on-one matchups, disrupting the Chiefs’ offensive rhythm.
Judy Battista of NFL.com pointed out the irony of the Eagles’ victory, noting that they beat the Chiefs using a formula that Andy Reid himself taught Philadelphia general manager Howie Roseman. Reid, a former offensive lineman, believes in building teams through the trenches, and Roseman followed that philosophy by constructing a dominant defensive line.
The Chiefs’ offensive line issues were further highlighted by the fact that they had to move Joe Thuney, an All-Pro left guard, to left tackle due to injuries. This weakened both positions and made it difficult for the Chiefs to protect Mahomes effectively.
Game of Adjustments
Eagles defensive coordinator Vic Fangio’s strategy was simple but effective: trust his defensive line to win their matchups and play zone coverage behind them. This approach allowed the Eagles to limit the Chiefs’ explosive plays and force Mahomes into making difficult throws under pressure.
According to Chris Simms, the Eagles played cover four (zone coverage) on 60% of their defensive snaps, the third-highest rate by a defense in a game since 2018. This indicated that the Eagles were confident in their ability to match up with the Chiefs’ receivers and prevent them from getting open downfield.
The Aftermath
The Eagles’ Super Bowl LIX victory was a testament to their dominant defense and their ability to exploit the Chiefs’ weaknesses. The loss served as a wake-up call for the Chiefs, who recognized the need to address their offensive line issues in the offseason.
Patrick Mahomes took responsibility for the loss, stating, “We didn’t start how we wanted to. The turnovers hurt. I take all the blame for that.” However, he also acknowledged that it was a team effort and that they would learn from the experience.
In the aftermath of the Super Bowl loss, the Chiefs made it a priority to improve their offensive line. They traded Joe Thuney to the Chicago Bears to create cap space and signed veteran offensive lineman Jaylon Moore. They also used their first-round pick in the 2025 NFL Draft to select offensive lineman Josh Simmons from Ohio State University.
A Lasting Impact
Super Bowl LIX will be remembered as a game where the Eagles’ defensive line exposed the Chiefs’ weaknesses and put immense pressure on Patrick Mahomes. The Eagles’ dominant performance showcased the importance of a strong defensive front and the impact it can have on a quarterback’s performance. While the Chiefs have since worked to address their offensive line issues, the memory of Super Bowl LIX serves as a reminder of the challenges they face and the importance of protecting their star quarterback.
