The Dallas Mavericks won their first Summer League game, although rookie Cooper Flagg wasn't thrilled with his performance.

The drafting of Flagg has reinvigorated Cuban, who sat courtside for Flagg’s summer league debut in Las Vegas.

League continues on Saturday, July 12 with No. 1 pick Cooper Flagg and the Dallas Mavericks taking on No. 2 pick Dylan Harper and the San Antonio Spurs.

Cooper Flagg appeared in his first pro game on Thursday night when the Dallas Mavericks played the Los Angeles Lakers at NBA Summer League. During the game (which the Mavs won by a score of 87-85), Flagg made a shot over Bronny James that got a lot of views on social media.

Former Dallas Mavericks owner Mark Cuban compared Cooper Flagg's debut to the early stages of Kobe Bryant's career.

Cooper Flagg went 5-21 in his Summer League debut, but Jason McIntyre says it’s time to relax and let him develop.

"I am so excited to see what he can do" - Grant Hill believes Cooper Flagg couldn't be in a better spot to thrive as a No. 1 pick originally appeared on Basketball Network.
