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

Per FanDuel Sportsbook, Flagg has been given -180 odds of being named the next Rookie of the Year. The No. 2 pick out of Rutgers, San Antonio Spurs guard Dylan Harper, has seen his odds dip to just the fifth-best among rookies (+1400) amid backcourt rotational uncertainty.

Flagg's first points as a pro came on a slam dunk with less than five minutes to go in the first quarter. The Mavericks guard finished with 10 points, six rebounds and eight assists in his debut. He played 32 minutes, making 5 of 21 field goals, missing all five of his three-point attempts.
