The sweater’s popularity skyrocketed, with many pointing out that she had worn it in an AT&T commercial alongside Cooper, which debuted during March Madness.
Duke’s freshman star isn’t the only Flagg making waves. His mother, Kelly Flagg, previously found herself in the spotlight for her spirited antics during one of Duke’s matchups against North Carolina. Now, with his grandmother’s courtside presence turning heads, it’s clear that the Flagg family embraces the spotlight just as much as Cooper does on the court.
As for the highly anticipated matchup, Duke entered the tournament riding a wave of momentum despite Flagg’s recent ankle injury. The ACC Player of the Year was officially cleared to play, providing a much-needed boost for the Blue Devils. Flagg, who has led Duke in nearly every major statistical category, returned with the weight of expectations on his shoulders—but also with his biggest supporters watching from the stands.
While Flagg’s performance remains the key to Duke’s championship aspirations, his grandmother’s viral moment added an extra layer of excitement to an already thrilling March Madness opener. If her sweater is any indication, the Flagg family is more than ready for the madness to continue.
