The duo's chemistry was pivotal in keeping the Chiefs' defense on its heels and establishing a commanding lead. Defensively, the 49ers made their mark with key plays that shifted the momentum. Deommodore Lenoir's interception was a crucial turning point, halting a potential scoring drive from the Chiefs and allowing San Francisco to extend their lead.
