LAS VEGAS — Imagine the buzz for the Knicks if Kristaps Porzingis were fully healthy entering training camp and had Kevin Knox waiting on him.

Knox can’t wait to meet — and play with — Porzingis. Perhaps Porzingis, too, will be motivated to get back sooner than later after watching clips from Europe. Porzingis FaceTimed with Knox the night he got drafted and they have kept in contact.

“I’m looking forward to playing with Porzingis,’’ Knox said Friday night at Thomas & Mack Center after summer league had ended for the Knicks. “I can learn from him and play with him offensively and defensively. He’s one of the best players in the league, so it will be fun to play with him.”

And not so fun for opponents. If there is a new optimism regarding the Knicks, it is the vision of a Knox-Porzingis forward tandem — two big men who can spread the floor in David Fizdale’s position-less offense.

Porzingis probably won’t play his first game until around Christmas, at the earliest, though the Knicks won’t know anything until mid-September when he returns from Europe. Knicks president Steve Mills said the seven-month mark from surgery is when a timetable can be more clearly set.

“I see they will complement each other very well,’’ Fizdale said in Vegas. “That’s not a bad pick-and-roll to run — a KK-Porzingis pick-and-roll.’’

Knox, who averaged 21.3 points and 6.5 rebounds this summer, wasn’t perfect. But the 18-year-old Knicks lottery pick silenced his doubters. There wasn’t an NBA talent evaluator — or Knicks summer-league teammate — in Las Vegas who didn’t believe the 6-foot-9 combo forward at least has a chance to be a No. 1 scoring option when he gets out of his teenaged years.

As Knicks shooting guard Damyean Dotson left the arena Friday after the team’s finale, he said, “He has that high ceiling. I’m just excited to see him at training camp. He’s only going to get stronger.’’

Knox, who shot 35 percent but got to the free-throw line often, will now take a breather, head to his hometown of Tampa, Fla., before ramping up in August.

“I did pretty well, I handled the ball on the pick-and-roll, showed people I could shoot the ball,” Knox said. “I’m probably getting a little stronger, working more on finishing. I’m getting by a lot of guys and being able to get to the basket, I want to be able to finish when I get there.”

Meanwhile, Fizdale will head to Latvia next Sunday to meet Porzingis.

On the visit, Fizdale plans to sit with Porzingis and show him a lot of film. He wants to show him summer-league footage, too, how he and Knox can become a dynamic duo for the next several years.

“It’s going to be a big part of the next step to show him the big picture,’’ Fizdale said of his trip. “How I want to utilize him, coach him, start building a relationship with him, a bond with him, a connection with him.”

Though Knicks fans chanted, “Michael Porter’’ as the Knicks came to bat at No. 9 last month, Knox in Vegas displayed all the upside the injured Missouri forward flashed in high school — sensational in the open court, getting to the basket with a soft 3-point shot.

Porter was in Vegas as a spectator and he may be spectator all season for Denver, which took him 14th as he recovers from back issues. Sources have indicted it would have been “reckless” to take Porter as a high as No. 9 after seeing medical reports soon before the draft.

The Knicks needed to take a player who would immediately show terrific potential as they embark on a 2019 free agency hoping to draw a max-worthy player, perhaps point guard Kyrie Irving, who watched Knox when the Knicks faced Boston.

“I thought I played really well where people who haven’t seen me, I showed I’m a versatile guy,’’ Knox said. “That’s what I like to work on in the offseason. I just want to build on this performance and get to the gym, watch film.”

Fizdale said, “He answered all the questions people had about him in summer league.”

Knox looked tired versus Boston, and the Knicks made the smart move in shutting him down for Friday’s finale against New Orleans.

“If I wanted to play, I would’ve played,’’ Knox said. “Fiz told me it was best to rest and sit and see everything you’ve seen from a sidelines perspective.’’

Though the Boston outing was his worst of the four, it could be a blessing in disguise. Celtics forward Semi Ojeleye, coming off a solid rookie season after being a second-round pick, used his physicality on the 215-pound Knox, who shot 5-of-20 and didn’t get to the basket nearly as often. Knox still managed 15 points.

Knox is already a quick study on Ojeleye.

“I learned a lot — I watched a lot of film on that game already,’’ Knox said. “Semi is a great defender one of the best defenders in the league. He guards LeBron [James], Giannis [Antetokounmpo]. It was good to go against him — one of the premier defenders. … I watched a lot of film from that game and will get better from it.

“It was great experience,’’ Knox added. “I learned so much from coaches, training staff. I learned most is the spacing. Spacing is totally different from college and high school. It was fun.’’

The Knicks marketing staff is now giving away free Knox “20’’ jerseys with purchase of a partial season-ticket plan. Indeed, Porzingis is happy to have another potential star in town.
