Here’s a juicy comparison to chew on over Memorial Day Weekend — courtesy of ESPN’s college basketball savant Jay Bilas.

Bilas sees a lot of 2018 MVP James Harden in Duke’s lefty 6-7 shooting-guard sniper, RJ Barrett, who should be available at No. 3 when the Knicks are on the clock at the June 20 NBA draft. In fact, Bilas still thinks Memphis has a rough decision with the second pick.

“He’s legit,’’ Bilas told The Post in a phone interview. “He’s worthy of being the No. 1 pick. He did things this year that hasn’t been done by a freshman. He handled the ball, ran the point, played off the ball. He did everything you can ask of a player. Barrett’s a lot like James Harden. His (outside) shooting is going to improve. He shoots a good ball. His mechanics aren’t broken. He’ll get much better.”

Bilas could be slightly biased. He was a Duke starting center from 1982 to 1986 and then coach Mike Krzyzewski’s assistant coach for three seasons thereafter.

The scouting naysayers suggest Barrett could find it more troublesome scoring as proficiently as he did at Duke because his 3-point shooting is still suspect, his athleticism is not off the charts for a player who piles up his points darting to the rack, and he’s not the most willing passer.

Bilas disagrees with those assertions.

“He’s athletic,” Bilas said. “He’s more than crafty. He’s athletic. It’s like saying James harden is not athletic. He’s absolutely athletic.”

The Post has reported the Grizzlies are leaning toward Murray State point guard Ja Morant over Barrett. Morant told The Post this week Memphis gave him no indication of their selection thinking in his meeting. Bilas said the Morant and Barrett debate is a really close call.

“Anybody with the No. 2 pick would have to think hard about it,’’ Bilas said. “If you’re not thinking hard about it, you’re making a mistake. There’s nothing wrong with someone who likes Ja at 2 but there’s nothing wrong with someone taking RJ either. It’s not an exact science.”

Barrett should really be going into his college freshman season and doesn’t turn 19 until mid-June. Bilas doesn’t think that is factored in enough when analyzing Barrett’s potential growth. Barrett averaged 22.6 points, 4.3 assists and 7.6 rebounds at Duke, becoming the first player in NCAA history to tally at least 850 points, 250 rebounds and 150 assists in a season.

“He’s essentially the equivalent of a high school senior,” Bilas said. “He reclassed to go to Duke. He was supposed to be in high school this year — similar to what (Marvin) Bagley III did the year before. He graduated high school early or he would have been a one-and-done player coming into this year.”

The only concerning part of his stat line is his 3-point shotmaking. Barrett logged a modest 30.8 percentage from behind the arc.

“He can play anywhere, you can put him in any spot and he can operate,’’ Bilas said. “He can initiate, he can play off the ball. He can do whatever you want him to do. The only thing right now, he’s not a consistent perimeter jump shooter. But the list of players we’ve said that [about] over the years who are in the Hall of Fame now is a long one.

“We said that about Michael Jordan, (Scottie) Pippen. We said it about a whole bunch of guys. Zion Williamson, Morant. Morant’s not a great shooter with his perimeter shot. Morant’s no Stephen Curry or Klay Thompson. (RJ) has every tool you want in a player.”

Defense is not an issue to Bilas because of Barrett’s length. Though he was not measured at the combine, his wingspan came in at 6-10 at a high school all-star event last year.

“A year ago he was the No. 1 pick,’’ Bilas said. “Ja is fantastic but I don’t think it’s a no-brainer that he should automatically go ahead of RJ Barrett. If RJ is the choice, it’s a helluva basketball player who has all-star potential.

“When you look at the way he rebounds, size, ability to get to the basket — he’s the only guy on that roster that didn’t miss a game. He played sick, hurt and played through everything.”

That said, Bilas said the Knicks may want to explore packaging the No. 3 pick if it means netting superstar big man Anthony Davis. The Post has reported the Knicks still have Davis on the radar.

“There’s so many variables going into that trade,’’ Bilas said. “It’s going to take a lot more than the 3 pick to get AD and have some assurance he’ll sign long-term. The No. 3 pick this year is a valuable commodity.’’

Johnny Dawkins, former Duke star and current head coach of Tacko Fall at Central Florida, weighed in on Barrett during an “MSG 150” appearance Thursday.

“He has a certain mindset,’’ Dawkins said. “He didn’t mind taking 20, 25 shots a game. That’s not easy. People think that’s an easy thing. You have to have a certain mindset, a certain killer instinct that I’m just going to be relentless throughout the game.’’
