Associate head coach Chris Carrawell has seen it before. The former Blue Devils teammate of big program names like Elton Brand, Jay Williams and Shane Battier returned to join Krzyzewski's staff in time for Williamson's supernova 2018-19 season, filled with highlight-reel dunks and levels of attention bordering on spectacle on his way to becoming AP national player of the year and the top overall NBA draft pick.
"I won't say Cooper is at that level yet," Carrawell said. "But I mean, this is how you know: when a non-basketball fan asks you in the grocery store: 'That Cooper Flagg guy ...' You're like, 'You don't watch basketball every day!' But they know, they know about him."
Andy Bedard, a former player at Boston College and Maine, remembers how the word spread, too. Not about Flagg as the NBA prospect; rather, it was about the standout youngster playing up multiple age levels in northern Maine. Bedard, who knew Flagg’s mother Kelly from her time playing at Maine, soon got a look at Cooper’s game.
"He was like third grade playing in a fifth- and sixth-grade league," Bedard said. “You wouldn’t know it because he was the same height if not taller than everybody else even with that difference because he was big at an early age. But he was playing like a guard. It wasn’t 'Go on the block and put it back in.' Watching him move, I’m like, 'Hmm, this is different.'"
Bedard went on to form the AAU team that would feature Cooper, his brother Ace, and Bedard’s son Kaden, and their families became close. That team eventually started beating the other top instate teams by lopsided margins before playing more games in New York, New Jersey, Connecticut and Massachusetts, and word began to spread about Cooper’s talent.
