He remained in the game for a few more minutes before sitting out the entire fourth quarter.

With D'Angelo Russell rested for the preseason contest, coach Jason Kidd seized the opportunity to see Flagg handle the ball. Kidd has been impressed by Flagg's performances, especially as a playmaker."When you look at what Cooper’s done here, it’s been really good," Kidd said before Monday's game. "We’ve put him in different situations - running the offense, running plays, playing off the ball. "There are things he has to improve. He’s not perfect yet, but being able to make plays and understand the game at a high level at 18 has been really cool to watch."Flagg recorded just one assist against the Jazz while starting at the point guard position. Perhaps the biggest takeaway was that the rookie committed zero turnovers, a glaring improvement after turning the ball over five times in his previous outing against the Charlotte Hornets.
