DURHAM, N.C. — Cooper Flagg said he hasn’t seen enough angles yet to give his monster dunk in the second half against Pitt an official grade, but the Duke freshman estimated it was about 8.5 out of 10.

His teammate Tyrese Proctor went a little further.

“That’s the best in-game dunk I’ve ever seen,” Proctor said. “It might be one of the best dunks, period.”

As soon as No. 4 Duke returned to the locker room after a convincing 76-47 win over Pitt, Proctor had the dunk displayed on his phone while the entire team gathered to watch it again.

Flagg was frustrated after a slow first half in which he picked up two fouls at the start, had to sit out for a long time and only scored five points in the end. He added foul No. 3 with 17:43 left and was visibly frustrated.

A moment later, he stole a pass near the baseline, drove the length of the court, launched near the top of the key and slammed home the dunk that electrified the crowd in a play Duke coach Jon Scheyer called ” “a Zion game,” recalls the excitement of former star Zion Williamson’s highlights at Cameron Indoor.

“We’ve had a few people over the years perform a few pieces that wowed everyone in the building,” Scheyer said. “It was one of those moments tonight.”

Flagg admitted he was “furious” after being warned for his third foul and said he may have taken out some frustration at the rim during the ensuing dunk.

He said he knew he was going to score midway through the court, but it wasn’t until he saw the defender in the paint that he decided to dunk. From then on, he said, everything was a blur.

“I almost passed out as soon as I jumped and all of it was just a flash,” said Flagg, who finished with 19 points and 10 rebounds. “I jumped, my mind went blank and everything happened very quickly.”

Flagg looked up at the crowd loudly celebrating the moment and was then surrounded by his teammates. Pitt’s Guillermo Diaz Graham was called for a foul during the game and Flagg made the ensuing free throw. After Pitt missed a layup on the other end, Flagg drilled another dunk to put Duke ahead by 14 points — although the second one wasn’t nearly as acrobatic as the first, which he said was a “top three” for him belonged.

“He gets angry, but at the same time he’s relaxed,” Scheyer said. “He loves being in the arena but he has an advantage now and it can happen quickly. We saw that tonight. He picked up his third (foul) and it just got him going.”

Duke dominated after Flagg’s heroics, outscoring the Panthers 37-21 after the dunk. Flagg’s second half included 14 points on 5 of 7 shooting, 7 rebounds and 5 assists. He was plus-16 at halftime.

After the game, which Duke finished with an 18-0 run, Scheyer emphasized that there should be no debate at this point about who the best player in the country is.

“He proved who he played with and how he did it in such a mature way,” Scheyer said. “He’s just so competitive and just brings out a lot of good things from his teammates.”
