The jersey worn by Dallas Mavericks rookie Cooper Flagg in the first half of his NBA debut was sold privately by Sotheby’s for $1 million, a record for a Flagg collectible and a record for a jersey sold through NBA Auctions. Flagg had 10 points and 10 rebounds in his first regular-season game, a 125-92 loss to the San Antonio Spurs on Oct. 22. This season, Flagg has become the NBA’s youngest player to score 40 points in a game and owns the single-game record for points scored by a teenager (49).
