Williams would then put the dagger into the hearts of the 49ers with a 38-yard rushing touchdown to put the game out of reach.

It’s the first Super Bowl victory for the Chiefs in 50 years. Kansas City hadn’t won since Super Bowl IV.

It is also the first Super Bowl victory for Andy Reid as a head coach. Reid’s failure to win the Super Bowl was a key storyline heading into the championship game. He had appeared in one while head coach of the Philadelphia Eagles but could never get over the hump and hold the Lombardi Trophy.
