Mahomes started the game out very tentatively despite an early rushing touchdown and looked second best to his opposite number Jimmy Garoppolo for most of the night. Touchdowns for the 49ers from Kyle Juszczyk and running back Raheem Mostert put them up in a comfortable position to win their sixth Super Bowl even as Mahomes struggled - throwing back to back interceptions on two consecutive drives.
However, in the fourth quarter the Chiefs defence came up big to stop the San Francisco offence and last year's league MVP Mahomes turned up even bigger to turn the game on its head. Not new to being down in the fourth quarter this season, the Chiefs quarterback led his side to a comeback on the biggest stage.
Down 20-10, Mahomes evaded a tackle and launched a 44-yard bomb downfield to find Tyreek Hill and start the ball rolling at third and 15 on their own 35-yard line. That turned into a touchdown for Travis Kelce - after another huge throw on third down from Mahomes - to cut the deficit to three.
On the next drive after the 49ers failed to score, Mahomes found Williams for a score which had to be reviewed, but was given to put the Chiefs ahead. The final nail in the coffin was delivered when a Jimmy Garoppolo pass was intercepted by Kendall Fuller and the Chiefs were able to run out the clock to win their first Super Bowl in fifty years.
After the game, Mahomes was effusive in his praise for the team, saying "We never lost faith. Everybody on this team, no one had their head down and we found a way to win in the end "
For 49ers coach Kyle Shanahan this was deja-vu in a sense as he was the offensive co-ordinator for the Atlanta Falcons when they famously blew a 28-3 lead against the New England Patriots in Super Bowl 51. "It was a tough loss and it hurts everybody in that room," said Shanahan. "We had opportunities to win and came up short. They were better than us, we can deal with that but we're obviously disappointed."
The Super Bowl was not only full of fireworks during the game but also at halftime as Latin superstars Jennifer Lopez and Shakira put on a spectacle in what is essentially the biggest concert of the year. Rattling through 20 hit songs in 15 minutes, the show was a much bigger hit than last year's Maroon 5 performance. The game was also notable for the number of celebrities in attendance including David Beckham, Floyd Mayweather, Kevin Hart, Jay-Z, Beyonce, and Marcus Rashford.
With this Super Bowl win, Patrick Mahomes becomes the youngest player to have won both the MVP and the Super Bowl - having done both within the first three seasons in the league. Chiefs coach Andy Reid won his first Super Bowl at the age of 61, after being in the league for two decades and seeing many of his sides come to the playoffs only to go back home disappointed.
In the end, a week that began with the passing of American sporting legend in Kobe Bryant, may have ended with the crowning of another in Patrick Mahomes.
