Cooper Flagg had a breakout game against the Milwaukee Bucks on Monday, but it was overshadowed by a no-call late in the contest. With 17.9 seconds left, Flagg came off a screen with Kyle Kuzma chasing him and fell on an in-bounds play. Kuzma intercepted the pass and scored on the other end to give the Bucks a three-point lead.Kuzma seemingly grabbed Flagg's jersey on that play, which led to the Mavericks rookie hitting the hardwood. The Mavericks could have taken the lead on that possession as the Bucks were out of fouls, and Flagg would have gone to the line, adding to his clutch total.Before this play, he scored a phenomenal layup over Giannis Antetokounmpo to give the Mavericks a one-point lead with 29 seconds left.However, the game ended 116-114 in the Bucks' favor. P.J. Washington had the chance to tie it up after Giannis Antetokounmpo fouled him on a 3-point play, but the forward only made his first shot from the line.Here's how fans reacted to the refs' gaffe, overshadowing Flagg's breakout game with 26 points (career high), nine rebounds, four assists and two steals:DUFF CO$MIC @DuffCosmicLINKCooper Flagg should’ve been at the line these refs would’ve called that for Giannis smhMalcolm @DaRealMQLINKRefs just cheated my boy Cooper Flagg!
