Purdy, on the other hand, handled pressure calmly. He escaped sacks on 80% of blitzes and converted 3rd-and-long twice. That kind of clutch execution matters especially when every possession counts.

This duel did more than score points. It shaped tempo and momentum. Mahomes delivered explosive plays. Purdy countered with composed drives. The clash of styles turned it into a strategic chess match not just football.

Ground Game Examination

Running Back Comparison

Christian McCaffrey went for 18 carries, 95 yards, and 1 TD (5.3 YPC). Isiah Pacheco chipped in with 14 carries, 60 yards (4.3 YPC), but punched in a short-range TD. In raw yardage, CMC stayed more reliable but Pacheco’s burst on zone read plays gave the kansas city chiefs vs 49ers stats nuance.

  • Purdy escaped pressure 3 times for 18 yards.

Neither quarterback leaned heavily on rushing. But when they did, it mattered disrupting coverage, extending drives, setting up play-action.

Blocking Effectiveness

San Francisco’s offensive line created 4 runs of 8+ yards before contact. Meanwhile, Kansas City’s line gave McCaffrey hits after only 2–3 yards. That’s the trench war in action: the 49ers vs kansas city chiefs match player stats reflect subtle yet game-changing yardage before first contact.

Passing Game Breakdown

Top Receiving Weapons

  • Travis Kelce: 8 targets, 6 receptions, 85 yards, 1 TD, 35 YAC.
  • Brandon Aiyuk: 7 targets, 5 catches, 60 yards.
  • Deebo Samuel: 6 targets, 4 catches, 55 yards, 1 TD.
  • Rashee Rice (Chiefs): 5 targets, 4 receptions, 70 yards.

Kelce’s role as Mahomes’s go-to is clear. He hauled in tough catches over the middle and picked up YAC. For the 49ers, Aiyuk and Samuel added depth and explosive flashes. Rice stepped up, too.

Explosive Passing Plays

Five plays went for 20+ yards (3 by KC, 2 by SF). The Chiefs’s deep ball connected with Kelce and Rice; the Niners turned one into a long touchdown to Samuel.

Pass Protection Metrics

  • Sack rate: Chiefs allowed sacks on 7% of dropbacks.
  • 49ers surrendered only 5%.
  • Pressures allowed: 12 for KC, 9 for SF.

Small gaps, but they add up. Kansas City’s higher pressure rate slightly elevated Mahomes’s risk but he still produced.

Battle in the Trenches

Offensive Line Performance

Win rates:

  • 49ers O-line: 78% pass-block win rate.
  • Chiefs O-line: 72%.

Few penalties, strong push at the line. San Francisco seemed a bit crisper, giving Purdy more clean pockets. That shows in the 49ers vs kansas city chiefs stats, where pass success on early downs favored San Fran by ~8%.

Defensive Line Impact

  • Nick Bosa: 1 sack, 2 tackles for loss (TFL), 3 hurries.
  • Chris Jones: 2 sacks, 1 TFL, 4 QB hurries.

KC’s interior D-line made Mahomes uncomfortable early. SF’s edge rushers gave Purdy glimpses of pressure, though KC struggled with containment on outside runs.

Run-Stopping Efficiency

  • Chiefs: 7 TFL, 2 forced negative plays.
  • 49ers: 5 TFL, 1 forced negative.

KC’s linebackers and DL clogged front gaps more effectively. That shows how tight the trenches were and how they influenced the kansas city chiefs vs 49ers stats by tripling up on stops behind the line in key moments.

Defensive Playmakers Spotlight

Secondary Matchups

  • Interceptions: Chiefs had 1, 49ers none.
  • Pass Breakups: SF: 4, KC: 3.
  • Coverage Grades (PFF): SF secondary held a +2.5 coverage grade; KC had +1.2.

Chiefs’ pick came on a forced throw and it swung momentum. But the 49ers’ tight coverage conversions slowed down key third-down opportunities.

Linebacker Contributions

  • Fred Warner: 9 tackles, 2 TFL.
  • Willie Gay Jr.: 7 tackles, 1 sack.

Warner’s leadership and sideline-to-sideline range shored up the middle. Gay’s sneak pressure on passing downs created micro-edges that sum up in situational dominance.

Turnover Battle

Chiefs forced:

  • 1 interception.
  • 1 fumble (recovered by DE Melvin Ingram).

They scored 7 points off turnovers. SF created 0 turnovers. That 14–0 swing is a massive tilt when you watch the 49ers vs kansas city chiefs stats and see how turnovers shift win probability by more than 20%.

Kicking Game

  • Harrison Butker: 3/3 field goals (longest 48 yards).
  • Jake Moody: 2/2 (longest 45 yards). Made a critical 38-yarder late in the 4th.

Punting Efficiency

  • Chiefs Punter: 42.3-yard net average, 2 punts inside the 20.
