Kevin Durant and Kyrie Irving are in Brooklyn. Kawhi Leonard is in Los Angeles. Kemba Walker is in Boston.

The summer went about as poorly as possible for the Knicks, but Kristaps Porzingis may have just delivered an even more painful dagger.

“I feel great physically. I feel 100 percent,” the Mavericks star told reporters on Monday. “I feel probably better than I ever have in my life.”

The 24-year-old, who was expected to be the face of the Knicks franchise for the next decade, is preparing for his first game since tearing his ACL in February 2018 fresh off signing a five-year, $158 million deal with Dallas, which acquired Porzingis in January’s trade with New York. At Monday’s Media Day, the 7-foot-3 forward said he has no physical limitations going forward.

“It’s been a long time since I’ve been out, but I’ve been putting in work throughout this rehab process,” Porzingis said. “I’m extremely excited to be back on the court and to remind everybody what I’m capable of doing.”

Porzingis had begun to reveal his ceiling in his third season, being named an All-Star while averaging 22.7 points, 6.6 rebounds and 2.4 blocks, prior to suffering the career-altering injury. Porzingis has been practicing with the Mavericks since late last season, but the team opted to ease the big man back into action. Now, nearly 20 months removed from the injury, the Mavericks still may be cautious using Porzingis on back-to-back nights.

“If I had a gun to my head, I would say that there’s a good chance that we will be very careful on back-to-backs, particularly to start the year,” Mavs coach Rick Carlisle said. “But I don’t know for sure. I don’t know how he’s going to be feeling at that point. He may be insisting on playing, but I do believe in his case and in the case of any player like that, the Mavericks or whatever team is going to err on the side of caution.”

Porzingis’ arrival creates one of the league’s most intriguing duos, with the Latvian paired with reigning Rookie of the Year Luka Doncic. Last season, Doncic, 20, averaged 21.2 points, 7.8 rebounds and 6.0 assists.

“I think it’s going to be pretty simple; just the two-man game,” Porzingis said. “Whatever it is, pick-and-roll; pick and pop. We’re going to have to read each other.

“That’s where I think we’re going to have to find out that chemistry, where he knows when I’m going to pop and when I’m going to roll…. We can really mess up team defenses like that. If they want to switch, he can attack the mismatch; or I can attack the mismatch. I think it could be a nightmare for the teams going forward. We just have to develop that chemistry on the floor.”

The young stars will have plenty of time. But Porzingis doesn’t plan to wait.

“In our mind, we have to make the playoffs. That’s the goal for us. There is no other goal for us,” Porzingis said. “We believe that with this group, we’re capable of that.”
