Flagg’s game-worn jersey from his NBA Summer League debut last July is up for sale in Heritage Auction’s Winter Platinum Sports Auction, which concludes March 1.<\/p>\n
DALLAS \u2014 Cooper Flagg called it “one of the worst games of my life.”<\/p>\n
But that won’t matter much to well-funded memorabilia collectors, who will only care about one thing: It was his first game<\/a>, whether that was good, bad or anything in between.<\/p>\n Flagg’s game-worn jersey from his NBA Summer League debut last July is up for sale in Heritage Auction’s Winter Platinum Sports Auction, which concludes March 1.<\/p>\n The bidding is already up to $40,000<\/a>, and Heritage estimated its value at $150,000 and up. The jersey (see photo above) comes with a letter of authentication, which was obtained by photo-matching the jersey to Flagg’s first pro game against the Lakers on July 10 in Las Vegas.<\/p>\n Flagg had an uneven debut with 10 points, six rebounds, four assists and three steals. The No. 1 overall pick wasn’t exactly thrilled with the performance.<\/p>\n “I would say that might be one of the worst games of my life,” he told ESPN after the game<\/a>. “We got the win, so that’s what really matters to me.”<\/p>\n Flagg, however, has already blossomed into a star in his rookie season, averaging 20.4 points per game, 6.6 rebounds and 4.1 assists for the Mavericks. Before the All-Star break, Flagg was on an incredible run of scoring, including a 49-point output against the Hornets on Jan. 29 and multiple 30-point games in the first week of February.<\/p>\n
