Topps released its 1/1 Debut Patch Autograph card from Cooper Flagg's debut with the Dallas Mavericks, a game in which he had 10 points and 10 rebounds against the San Antonio Spurs. The card features the debut patch that was placed on that jersey, and was placed in Topps' Chrome Update set that dropped on Thursday. In preparation for that, the Dallas Mavericks have offered the house in order to be the ones to get the card. The Cooper Flagg Rookie Debut Patch Autograph Card is officially out there. That gave Cooper Flagg a close Rookie of the Year win over his college teammate, Kon Knueppel, who led the NBA in three-pointers made.
