It is down to the last two teams standing.

It has been quite a remarkable turnaround for the San Francisco 49ers.

Raheem Mostert rushed for 220 yards and four touchdowns to make quarterback Jimmy Garoppolo mostly a spectator, Nick Bosa harassed Aaron Rodgers from the start and the 49ers beat the Green Bay Packers 37-20 for the NFC championship on Sunday.

The 49ers (15-3) advanced for the first time in seven years and will play the Kansas City Chiefs in two weeks in Miami for the championship.

In Kansas City, Chiefs quarterback Patrick Mahomes did his usual superb job passing, but it was his 27-yard tap dance down the left sideline late in the first half that gave the Chiefs their first lead.

From there, they outran the run-oriented Tennessee Titans and star back Derrick Henry for a 35-24 victory Sunday in the AFC Championship.

In San Francisco, “Our team, it’s incredible to be a part of,” Garoppolo said. "We can win so many different ways. Raheem, those guys up front, the tight ends obviously were just dominating tonight. It was fun".

The Niners won just 10 games in the first two seasons under coach Kyle Shanahan and general manager John Lynch, going 4-12 last season after Garoppolo went down with a season-ending knee injury in Week 3.

Now, San Francisco is one of two teams remaining after delivering a second thorough beating of the season to Rodgers and the Packers (14-4).

Bosa, the prize for last year's rough season as the No. 2 overall pick, helped set the tone when he ended Green Bay's second drive of the game with a 13-yard sack of Rodgers.

Mostert, a former special teams standout, did much of the rest in a remarkable redemption story for a former surfer who was cut seven times and carried the ball only eight times in his first three seasons in the NFL.

But he has become a key part of the NFC's top team this year, leading the Niners with 772 yards rushing in the regular season and delivering a performance for the ages in the NFC title game.

He had the second-most yards rushing in a playoff game to Eric Dickerson's 248 for the Rams on Jan. 4, 1986, and was the first player to rush for at least four TDs and 200 yards in a playoff game.

“You know, honestly, I just woke up like it was any other game," Mostert said. "It was one of those things where hey, once we all get in a groove, we’re just going to keep it riding, keep it going and that’s what we did.”

He got started when he burst 36 yards on a third-and-8 trap play to open the scoring on San Francisco's second drive and kept ripping off long runs behind impressive blocking.
