Kidd: It s normal for Flag to make mistakes, but it s amazing that he s so calm at the age of 18.

In the NBA Summer League, the Mavericks defeated the Lakers 87-85. Mavericks coach Kidd talked about Flag's debut performance in a summer league in an interview.

Kidd said: "You should hand the ball in his hands like Flag, who can control the ball, shoot and pass the ball. He has excellent decision-making skills, which was the case in Duke and the same in high school. You will see this tonight. Of course, he will make mistakes, which is normal, but as an 18-year-old player, the calmness he showed is simply amazing."

In this game, Flag made 5 of 21 shots, 0 of 5 three-pointers, 0 of 1 free throw, and scored 10 points, 6 rebounds, 4 assists and 3 steals.
