Cooper Flagg's summer league debut wasn't perfect. But there were flashes of greatness, and at this stage the Mavericks would be wise to let him fail.

The best of them was French point guard Nolan Traore, who looked like a guy who has played against men before (he played professionally in France last year) and was comfortable, finishing with 13 points on 3-of-5 shooting and getting to the line six times. It was a promising start.
