For much of Sunday's Super Bowl, the Kansas City Chiefs appeared on the verge of defeat.
A sluggish offense failed to produce a touchdown in the first half then turned the ball over on the first drive of the second half to keep the San Francisco 49ers in control of the game. But Kansas City's defense kept San Francisco in check, allowing just enough room for Patrick Mahomes to mount a comeback.
The Chiefs faced a narrow path to victory that required execution in critical moments and a few breaks to go their way.
