There’s one Knick adapting wonderfully to David Fizdale’s attempt at a high-tempo, spread-the-floor offense.

John Jenkins of the Westchester Knicks.

Jenkins, a 3-point shooting machine, is tearing up the G League the same way Trey Burke did last season. The 27-year-old posted a franchise-record 44-point game and leads the G League in scoring with 30.0 points for players with at least four games. He’s shooting a Steph Curry-like 52.8 percent from 3-point land and 95 percent from the free-throw line.

An undersize 6-4 shooting guard, Jenkins hasn’t stuck in the NBA, having played in limited stints with Atlanta, Dallas and Phoenix. But last season he tried the Spanish League to get big minutes as part of his scheme to get back into the NBA and said it was “the best decision I ever made.’’

As part of the Knicks’ G League philosophy, Westchester coach Mike Miller runs the same offense as the big club.

“Anywhere I can get a real opportunity and chance to play at this stage of my career,’’ Jenkins told The Post. “But with the Knicks, I’m trying to stay in the moment. I’m on the Knicks and I’m at the (Tarrytown) facility all the time. I’d love to be part of them at some point during the season. It would be great to be in the Knicks uniform and play at Madison Square Garden. That’s a dream come true for a lot of kids. They’re the team I want to play for. Hopefully I can make that happen.”

Jenkins starred for the Blazers’ summer-league team in Las Vegas that won the championship in July. But the Blazers, who visit the Knicks Tuesday, added guards in the draft and free agency and their roster was stocked. The Blazers are still monitoring Jenkins, an NBA free agent despite signing a Knicks training-camp Exhibit 10 contract. Jenkins will leave Westchester next week to compete on the Team USA World Cup qualifying team that is playing in Uruguay.

The Knicks are ranked 28th in 3-point shooting (31.7) and Fizdale has frequently mentioned it being a team weakness.

“I definitely watch all the games and feel I can help when the time comes,’’ Jenkins said. “The offense Fizdale has us running is perfect for me. He has us spread out and open and it’s made for a shooter. I’m definitely trying to take advantage of the offense here and hopefully I can do the same thing for the big Knicks soon.’’

Though Jenkins hasn’t stuck on an NBA squad, he believes his time is now — with pace and 3-point shooting all the rage.

“I think it’s almost perfect timing with Steph, Klay [Thompson], they’re making it a lot easier for guys like me to stay in the league and get back in the league,’’ Jenkins said. “I’ve knocked down 3s my whole life. Now it’s more prominent than ever. Hopefully teams see that and help me in the future.”

What teams also want to see, Jenkins believes, is consistent defense and more playmaking — which he feels he’s accomplished in Westchester despite the gaudy scoring numbers. The Knicks suspect a more veteran team may sign Jenkins, especially if there’s an injury.

The Knicks haven’t ruled out Jenkins for later on once they get their 15-man roster in order. In December, one Knicks player must be cut to make room for rookie guard Allonzo Trier, who is on a two-way G League contract that will be converted. Trier was supposed to play in Westchester alongside Jenkins, but the undrafted Arizona rookie has proven himself ready for the NBA.

After the trade deadline, some players who don’t have a Knicks future could also be in jeopardy of being waived to open a roster spot. Courtney Lee, who has missed the entire season, is finally practicing but he’s a trade/stretch-provision waiver candidate.

One NBA scout said Jenkins’ true shooting skill is “a quick release’’ — something that can’t be taught. Jenkins believes a 3-point shooting specialist will be in demand as long as other parts of his game are noticed.

“The biggest thing for me was defense and I’m trying to show that the most in Westchester,’’ said Jenkins, who is averaging 1.6 steals, 4.0 rebounds and 2.7 assists.

After struggling in training camp, Knicks second-year center Luke Kornet also has put up big numbers in Westchester in his six games. Kornet, who is on the 15-man roster after being a two-way player last season, is averaging 19 points and 9.4 rebounds.
