Charles Barkley isn’t sure if Kevin Durant and Kyrie Irving have thick enough skin for New York, but, if they do, he thinks they could end up as legendary as Mark Messier.

Every year, prior to the NCAA Tournament, Turner and CBS hold their March Madness media day, and this time around two things are certain: Barkley will have a crowd surrounding him, and he will make headlines.

That’s what he did Tuesday, when he was asked a question by Sports Illustrated’s Jimmy Traina about Durant and Irving potentially joining the Knicks as free agents.

“I don’t think Durant or Kyrie are tough enough to play in New York,” Barkley said. “Kyrie’s a very good player. Kevin’s a great, great player. But I’m not sure they have the mental makeup to play in New York. Those guys are complaining about the media asking questions. Maybe New York isn’t for them.”

Later, when The Post followed up with Barkley, he expanded on his thoughts, invoking the brighter side of playing at the Garden, while summoning memories of 1994.

“What is going to be interesting is: Do Kevin and Kyrie have the mentality to play here?” Barkley said. “That, to me, is going to be the biggest question. There is no doubt in my mind that if you can win here, you are set for life.

“If they come here and get a No. 1 draft pick, high pick, whatever, and if they were to win a championship in New York, they would be like Mark Messier. I betcha Mark Messier is never going to pay for a drink his entire life. It is going to be a fascinating thing. If they can handle the pressure and they can win. They just would have to win one in the next five years and they would be golden.”

During Barkley’s one-on-one with The Post, he gave provocative opinions on other items, as well:

— What did he make of Knicks owner James Dolan’s confrontation with the “sell the team” fan?

“[Dolan] just has thin skin, plain and simple,” Barkley said. “He was just wrong. You can’t do what he’s done and not expect criticism, period.

“The NBA should reprimand him. We get to the point where he has not done a good job. You can’t just throw everyone out that says bad stuff to you, period.”

What should the reprimand from the NBA be?

“You have to say something publicly,” Barkley said. “I think a fine is appropriate. You can’t just get mad every time a fan says something to you.”

— Duke’s Zion Williamson has been compared to Barkley as a player. What does he think about that?

“I think he is more talented than I am,” Barkley said. “I think he is a lot more talented and explosive. It is going to be interesting what position he is going to play in the NBA. I think it would be easier for him to play in my day because we were just big, strong, talented guys beating the hell out of each other. I’m trying to figure out what position he is going to play in the NBA.

“I”m smart enough to know that it would be a lot harder for me to play in the NBA today, chasing those three and fours, which he is going to have to do. I think that is going to be a question mark with him.”
