At just 19 years old, Cooper Flagg has already established himself as a generational talent with an old-school approach to getting buckets. Facing his former Duke teammate Kon Knueppel in Dallas, the rookie phenom put together the performance of a lifetime against Charlotte. He hammers home a driving dunk in the second quarter, then caps his historic evening by burying a clutch pullup three with 33 seconds left to tie the game at 121. Flagg's 49 points shattered the NBA record for most points by a teenager, breaking Mark Aguirre's Mavericks rookie franchise mark, though he would later top this mark with a staggering 51 on April 3, 2026.
