When the Kansas City Chiefs were knocked out by the New England Patriots in the AFC Championship Game last season, their quarterback, 23-year-old NFL MVP Patrick Mahomes, promised to come back and make the Super Bowl next time. Congratulations to him for keeping his word.

Congratulations also to coach Andy Reid for finally putting a Vince Lombardi Trophy in front of his 222 wins – both regular and playoff seasons. 

And congratulations most of all to the Kansas City Chiefs for winning their first Super Bowl championship in half a century after defeating the San Francisco 49ers 31-20 at Hard Rock Stadium in Miami, Florida on Sunday night.

Mahomes was selected the Super Bowl MVP after completing 26 of 42 passes, throwing 286 yards and accounting for three touchdowns (two via passing and one by rushing).

His counterpart from the 49ers side, Jimmy Garoppolo, was 20-31 in passing and led to one TD in the 219 yards he threw.

The 49ers scored first in the game, but not through their favorite rushing – the team confused their own rhythm trying to control the pace of the game. Robbie Gould gave the 49ers 3-0 lead via a field goal in the first quarter.

The Chiefs' counterstrike came sooner than expected. Since the 49ers tried everything to contain Mahomes' intimidating passing, the 2018 NFL MVP decided to give them a surprise as he achieved Chiefs' first TD by rushing in the team's second drive. Then as Harrison Butker scored another three points for the Chiefs via a field goal, the lead was expended to seven (10-3).

Trailing seemed to straighten out San Francisco's thinking. The team continued to drop first down via smart rushing. As they opened new prospects on the ground, Garoppolo began to throw more threats. One of these threats was turned into a TD by Kyle Juszczyk before the end of the second quarter.

The Chiefs and the 49ers went 10-10 in the first half.

San Francisco continued to press hard on the ground in the second half and their efforts soon paid off. Thanks to another field goal by Gould and a rushing TD by Raheem Mostert. San Francisco established a 10-point lead (20-10) and kept the lead until the fourth quarter. Meanwhile, Mahomes, who allowed no interception in this season's playoffs, saw one of his passes intercepted by Fred Warner.

More began to expect San Francisco to win their sixth Super Bowl title in franchise history to match the Pittsburgh Steelers and the New England Patriots.

That's when Mahomes began to stand out and cast his magic. His two passes helped Tyreek Hill rush for 60 yards. Though Tarvarius Moore stopped Kansas City from scoring the first time, Travis Kelce did not let the 1-yard opportunity go and narrowed the score difference down with a TD.

Following the next wild goose chase by the 49ers, Mahomes first found Watkins with a 38-yard deep pass and then helped Damien Williams score the team's third TD, reversing the situation completely.

Trailing 23-20, the 49ers were again confused – they did not have enough confidence in the ground especially when the Chiefs paid more attention to it. Neither could they bet on passing, not only because of Garoppolo's defect, but also because they did not want Mahomes to come back to the field too quickly.

When Garoppolo was sacked, the 49ers lost most of their hope for the game. When Williams added another TD under his name, the game already became a foregone conclusion.

Having established a decent lead before watching the opponents put up an exciting comeback was nothing strange to Kyle Shanahan, head coach of the 49ers.

"Those guys are hurting in there, just like I am. We all are (hurting) right now. It's tough when you lose a Super Bowl, but I'm so unbelievably proud of those guys, what they've done all year. I've been coaching a while and it's as special a group as I've ever been around. It's tough that it had to end today in the way it did," Shanahan said after the game.

By contrast, as the winner this time, Reid enjoyed the chants of Chiefs fans at the stadium. "This is what it's all about. What a great team, great coaches. Appreciate every bit of it," he said.

On his side also stood 24-year-old Mahomes, the youngest Super Bowl MVP winner. "It means so much to me to do something like this for Kansas City and all its fans in all the states around Kansas City. The Chiefs brought me here and believed in me from the beginning. And all I've wanted to do since then is to reward their faith in me by winning a Super Bowl," said Mahomes.

Now the only question is, what will the Chiefs do to keep this young genius who changed their franchise history?
