There’s a new Jets duo in town.

Breece Hall and rookie Braelon Allen are now the headliners for the Jets offense, and they may soon be called the B&B boys.

Hall, the third-year back, is known for his speed and quickness, while Allen, a 20-year-old rookie, is what Robert Saleh calls a “bulldozer.”

Together, they scored all three touchdowns, one of which came on a reception before Allen made the game-winning ground ball, in the Jets’ 24-17 win over the Titans, providing a taste of what the future holds.

It’s been 30 years since the Jets had two running backs score touchdowns in the same game — since Richie Anderson and Johnny Johnson both caught one from Boomer Esiason against the Dolphins in 1994.

It’s been a significant difference for Hall, who carried the rushing load last season while Dalvin Cook failed to become the expected complement. In each other, Hall and Allen have found a friend and a training partner.

“(Allen) was shy and quiet at first. And then he realized how much I was fooling around, how crazy I was,” Hall told The Post on Tuesday. “I feel like he’s developed a little bit quicker than I did my rookie year. … He’s really smart, understands the offense from a whole standpoint now. It’s just great to see him get some (opportunities). The ops he’s gotten, he’s played ball, so I’m definitely proud of him.”

Allen on Sunday became the youngest NFL player to score multiple touchdowns in a single game and the first Jets rookie to score both receiving and rushing touchdowns in the same game.

“I knew who he was when we drafted him because I had heard about this 17-year-old kid who played at the University of Wisconsin when I was in Green Bay. I couldn’t believe it,” Aaron Rodgers said of Allen. “It’s a good reminder of how special it is to still be playing at 40.”

The duo is on track to become an offensive powerhouse under new running backs coach Tony Dews, and will be tested on Thursday against the Patriots, who have allowed the second-fewest rushing yards (116) this season at 3.3 yards per carry.

“You couldn’t ask for a better situation to step in with a guy like Breece,” Allen told The Post. “The success that he had early in his career was obviously something that I wanted to emulate. So you couldn’t ask for a better person to have in your corner.”
