The night before the Patriots take the field, their fans from all over are already arriving at Gillette Stadium.
One family travelled from Arizona to watch the team's first playoff game.
They say they're looking ahead to another AFC Championship.
"Got TB, got Jules, Hogan, everybody. We're going to get this," the family said.
This could be the game that sends the Patriots to the AFC Championship for the eighth year in a row.
"Oh they're going to win," another fan said.
To win, they'll have to take down the Los Angeles Chargers in what will be just the fourth playoff meeting between the teams.

Tom Brady and Chargers quarterback Philip Rivers will set an unusual record; their combined age of 78 makes them the oldest pair of quarterbacks to face each other in an NFL playoff game.
"He's an emotional leader. He always gets those guys going. They always have a good offense," Brady said.
But Patriots fans say they aren't too worried.
"I think the Patriots will win by a touchdown," one fan said.
"I got a good feeling about that," another fan said.
That's what fans say they've come to expect during playoff season: a win here at home that could send them to another Super Bowl.
"Let's go Pats! Woo!" the family from Arizona said.
The cold weather is also giving fans some extra confidence as they head into Sunday's game. They say the Patriots are used to the New England weather, but a warm weather team like the Chargers may not do so well.
