A resurfaced video shows a 13-year-old Flagg running basketball drills while wearing a Mavericks t-shirt. Despite barely being a teenager, Flagg is shown running back and forth across the baseline to defend a corner three-point shot.

NBA fans on X chimed in with their reactions to the Flagg-Pippen comparison as it grabbed attention on social media. One user commented that Flagg's ability to take over a game is more reminiscent of LeBron James than Scottie Pippen, while another questioned whether Flagg is the same type of "quick-twitch" athlete Pippen was in his prime.
