Jamison Crowder and Ty Montgomery’s Jets debuts didn’t last long.

But Sam Darnold’s two new weapons made sure to introduce themselves before getting the rest of the night off.

With the Jets first-team offense only playing one drive in Thursday’s preseason opener — a 31-22 loss to the Giants at MetLife Stadium — Crowder and Montgomery made the most of it, showing a glimpse of the offense Adam Gase hopes to boast in his first year at the helm.

Of course, the Jets’ biggest prize of the offseason, Le’Veon Bell, was held out of the game, but Crowder and Montgomery welcomed themselves to the green and white in no time, keying a seven-play, 75-yard drive that ended in Crowder’s 3-yard touchdown catch for the 6-0 lead.

“That’s really as good as it can get,” Crowder said. “We got a lot of weapons in this offense. My main thing is just play my role, be as much of a viable target for [Darnold] as I can. So whenever I get the opportunity, I’m going to take full advantage of it.”

Of the seven plays the Jets ran on the way to the end zone, Crowder and Montgomery combined to touch the ball on six of them, with a Darnold pass to Chris Herndon the only outlier. Montgomery took two carries for 7 yards and caught a 5-yard pass, showing ever so briefly the Swiss Army knife he can be in Gase’s offense.

“I think we accomplished what we wanted to accomplish,” said Montgomery, the former Packer who signed a one-year, $895,000 deal with the Jets. “Felt good to get my feet wet.”

Crowder caught both passes thrown to him for 31 yards, breaking loose on one of them for 28 yards. His touchdown came with some help from Quincy Enunwa on a pick play, getting Giants cornerback Julian Love out of position so he was free to haul in the short pass from Darnold.

“Ty and Jamison are both really good players,” Darnold said. “We have a ton of good players on offense. For them to play the way they did, I didn’t really expect anything less.”

Crowder could become Darnold’s favorite receiver to throw to this fall, a veteran target in the slot who signed a three-year, $28.5 million contract. The 26-year-old is coming off a down year last season with the Redskins, when he was hampered by a nagging ankle injury, but looked strong Thursday night.

“He can do all the things you need him to do,” Gase said. “He has something about him. He’s a veteran player that just knows how to get it done for the quarterback.”
