Last night the New England Patriots made history by becoming the first team to reach 10 Super Bowls.
But the AFC championship game against the Jacksonville Jaguars was far from an easy ride.
The team from the AFC South had been one of the league's surprise packages this season, finishing 2017 with a record of 12-7 to reach the playoffs.
After shocking the Pittsburgh Steelers last week with a 45-42 win at Heinz Field, the Jaguars came to Gillette Stadium as true underdogs once again.
Their incredible defense has been the reason many believe that they made it to the championship game and it's easy to see why.
Jacksonville finished the season as the league's top passing defense in terms of yards allowed and they were second when it came to points allowed, total yards and sacks.
But on Sunday night, it was actually the Jaguars offense that caused a lot of problems for the Patriots.
In fact, the home team only led twice in the game, once 3-0 after the first drive, then again with less than three minutes on the clock, 24-20. That means the Jaguars led for almost 50 minutes of the game.
But somehow, once again, New England, led by quarterback Tom Brady and head coach Bill Belichick, dug deep in the fourth quarter to secure the victory.
And once the game was over, wild celebrations broke out in Foxborough as the Patriots won their second straight championship game.
Well, it was wild celebrations for everyone but Belichick.
The Patriots coach is famous for showing little to no emotion on the sideline, but this game, that was so close to going the Jaguars way, must have been special.
He did break character briefly, frantically clapping his hands when Dion Lewis ran for a first on third down with just over a minute to go, effectively sealing the victory for New England.
But it's what Belichick did after the game that has caught attention from a lot of fans. As has become a familiar sight at Gillette Stadium, the AFC championship trophy was presented on the field.
It was first handed over to Robert Kraft, the team's owner, who made a speech and held it above his head.
He then passed it to Belichick, but the coach clearly doesn't have time for the conference trophy, handing it straight over without even looking at it.
After winning a very close game, most coaches would be pretty relieved. But not Belichick. If the Patriots go on to lose the Super Bowl, the AFC championship trophy becomes a runners-up award.
And finishing second is clearly not in Belichick's plans. He's already focused on the Super Bowl in two weeks time and it's his attitude to winning the AFC that shows exactly why he's become a serial winner.
