Is there another road other than “The Road to Zion?”

While Knicks fans are going gaga over Duke man-child and potential No. 1 pick Zion Williamson, college basketball analyst Seth Greenberg is saying nah and hailing Ja.

That is Murray State sophomore point guard Ja Morant, climbing ferociously up the mock-draft boards alongside some of his highlight dunks. And the 6-foot-3 point guard is eliciting superlatives from ESPN’s esteemed college expert Greenberg, the former Virginia Tech coach who hails from Long Island.

In an interview with The Post on Monday, Greenberg used the word “ridiculous” to describe Morant a half-dozen times, particularly in regards to the point guard’s court awareness.

“His vision is just ridiculous,” Greenberg said. “His athleticism is phenomenal.”

Morant is averaging 23.1 points, 10.7 assists and 6.3 rebounds — dazzling statistics in the underwhelming Ohio Valley Conference. The 19-year-old is shooting 54 percent, though just 30.8 percent from the 3-point line.

“He’s not a 3-point shooter yet, but he can get anywhere he wants,” Greenberg said.

Greenberg has seen Morant since high school in South Carolina. Morant never got major-conference attention, according to sources, because of academic issues.

“At times, he can be a bad decision-maker, but he’s explosive, long, ridiculous vision and is shooting the ball much better [than as a freshman],” Greenberg said. “He could be disruptive defensively with his length. His second gear is ridiculous. His burst is ridiculous. The best thing is vision. He gets guys buckets.”

He also gets turnovers. In a game versus Alabama, he notched 10 turnovers but also had 38 points, five assists and nine rebounds.

“He’s got to do so much for his team — he’s got the ball in his hands so much — but at times, he can be a risk-or-reward decision-maker,” Greenberg said. “You can’t always hit home runs. Sometimes you have to hit singles, get the hockey assist.”

According to a source, neither Knicks president Steve Mills nor general manager Scott Perry has seen Morant play live for the Racers who play their home games in Murray, Ky. But before the Knicks’ West Coast trip, Mills and Perry sat down to watch reams of Morant tape.

Knicks scouts have seen Morant and are expected to have a representative at his game Thursday at Eastern Illinois while the Knicks battle the Wizards in London.

The comparisons have ranged from Elfrid Payton — a former Perry pick — to Russell Wesbrook. Morant has soared to No. 2, behind only Williamson, in a mock draft conducted by nbadraft.net. The Knicks, at 10-33, are tied for second-worst record in the NBA and all but assured of a top-five pick under the new lottery format.

“The speed, explosiveness, vision and fearless way about him, can he be a Russell Westbrook?” Greenberg said. “That’s what some people are comparing him to as an explosive athlete. He’s significantly better than Payton, but I’d never compare anyone to Westbrook.”

The red flag is competing against the likes of Jacksonville State and Austin Peay. But Greenberg saw his games versus Alabama and Auburn, and said Morant was still superb. He more than held his own against Auburn’s Jared Harper and a tough defender in Alabama’s Herbert Jones.

“No one stopped him from getting the ball when he wanted and where he wanted,” Greenberg said. “No one stopped him getting in the lane or making plays in transition. Against the best teams he played against, he’s been his very best. That’s the key.

“Against Alabama, he got 38 and 10 turnovers and is 16-of-29. He gets 38 and doesn’t make a 3. You know what I mean? He’s a 2-point maker. He’s going to be a high lottery pick because he does freakish things.”

Speaking of freakish, the runaway hype on Williamson is getting to Greenberg. For a club in desperate need of a point guard such as the Knicks, Morant might turn out to be a sound addition.

Greenberg said of the 6-8 Williamson, “I don’t think he’s a no-doubt-about-it.

“This is not a good draft. It really isn’t. In this draft, you probably do [take Zion No. 1]. He’s fun to watch, explosive and doing things we haven’t seen in a long time. But I grew up watching Dr. J. I don’t get excited about dunks.”

Greenberg listed his Zion concerns, saying, “When does a guy like that not have a pull-up game? And he isn’t an NBA 3-point shooter yet.

“[Zion] has great passion and is Magic [Johnson]-esque in his personality. He competes on the defensive end and rebounds ferociously. But he’s not going to walk in and take over. Is [Zion] going to fix the Knicks? I don’t think so. Is he going to even do what Luca Doncic has done? I don’t know.”
