"He was the best player on the floor," said David Thorpe, Roberts' coach and personal trainer at the IMG Academy. "He was unguardable and was attacking people.
"That's the most I've seen him play like (the San Antonio Spurs') Tony Parker. He'll never be as good as Tony Parker, but that's who we want to get him to play like."
Roberts also helped his team to a victory Wednesday with 11 points on 4-of-9 shooting. In two games, he's hit 3-of-4 3-point attempts.
He'll play one more game today and will remain at the camp through Sunday with 70-plus other pro prospects to be tested and timed by NBA scouts.
