There’s a new Jets duo in town.

Breece Hall and rookie Braelon Allen are now the headliners for the Jets rushing attack — perhaps soon to be known as the B&B boys.

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

Together they scored all three touchdowns — each with one receiving before Allen scored the game-winner on the ground — in the Jets’ 24-17 victory against the Titans that lent signs of what the future could hold.

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

It has 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 play around, how much of a goofball I am,” Hall told The Post on Tuesday. “I feel like he’s been developing a little faster than I did in my rookie year. … He’s really smart, understands the offense from a whole standpoint now. It’s just been great to see him get some [opportunities]. In the ops he’s gotten, he’s been balling, so I’m proud of him for sure.”

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

“I knew who he was when we drafted him because I had heard about this 17-year-old kid playing at University of Wisconsin when I was playing 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 a path to be an offensive powerhouse under new running back coach Tony Dews, and will be tested Thursday against the Patriots, who have allowed the second-fewest rushing yards (116) with 3.3 yards per carry this season.

“You can’t ask for a better situation to come into with a guy like Breece,” Allen told The Post. “The success that he had super early in his career was obviously something that I kind of want to follow in. So, you can’t ask for a much better person to have in your corner.”
