As important as big man Kristaps Porzingis is to the Knicks’ future, the biggest beneficiaries of Jeff Hornacek’s hiring may be young point guards Jerian Grant and Tony Wroten.

Grant was last year’s first-round pick and Wroten was last year’s reclamation project. While the Knicks are sure to pursue big-name free-agent point guards, the hiring of a point guard-centric coach — and any gradual move away from the triangle toward the pick-and-roll — will only help the two 23-year-old prospects they already have.

“No question,” Grant’s father, Harvey, told The Post. “Jeff played in the league for years, coached in Phoenix. His system was mostly pick-and-roll. Jerian, once he learns the system, he can flourish in that system. And Jeff can tell him the ins and outs of being a guard in this league.”

The Knicks dealt away Tim Hardaway Jr. to get Grant at last year’s draft. Despite a mostly middling rookie campaign, his uptick came when he was finally turned loose at the end of the season, and getting a coach who tailored his Suns team to juggle point guards Eric Bledsoe, Isaiah Thomas and Goran Dragic has scouts hopeful.

“I’m pro-Hornacek. He’ll help all those guys if they listen,” said ex-Knicks scout Scott McGuire, son of team legend Dick McGuire. “Grant from Notre Dame is a terrific ballplayer. What they did with the Hardaway trade was a great trade. He didn’t play that much for a while, but he had more chances to learn and make mistakes, and as the season went on, he got better.

“He’s going to be a good player no matter whose system it is. I don’t know if he’s a point guard or a shooting guard, but I know he has a nose for the ball, and has a nice way about him.”

No Knicks player will salivate more than Grant at the thought of an up-tempo pace and pick-and-rolls. Grant is long, athletic and thrives in those kinds of sets. And despite a largely uninspiring rookie campaign, he showed flashes of ability when he started the final six games, averaging 3.7 assists and 14.5 points on 49.3 percent shooting, 36.8 percent from 3-point range.

His shaky jump shot is what caused him to be available to the Knicks in the draft, and it’s largely what he’s been working on for weeks in two-a-days at the team’s Tarrytown facility with ex-Nuggets shooter Mahmoud Abdul-Rauf.

“Jerian, this guy gets in the gym and he puts the work in,” his father said. “You have to be on the floor, you have to be on the floor and you’ve got to work through your mistakes and get that confidence. The last 12, 14 games, the fans in New York got to see what Jerian can do.”

Wroten, who was brought in while recovering from a torn ACL and is on a non-guaranteed contract, has worked on his own jumper with Allan Houston. He, like Grant, is slated to play in the summer league and said he expects to start next season.

The 6-foot-6 slasher has elite penetrating ability, and with his size and athleticism is used to getting to the hole almost at will against slower shooting guards and smaller point guards. He can attack from both spots; what the Knicks have to get him to do is be willing to facilitate from either.

“The challenge for Jeff is making Tony realize he has to make others better,” McGuire said. “As well as Tony [can play] individually, he has to become a facilitator for others for him to make the team more efficient.”
