ESPN analyst David Thorpe raved about Warren after the Summer League concluded.
"Warren looked like a five-year veteran playing against kids," said Thorpe. "Warren also moved smartly without the ball in half-court sets, something he did well at North Carolina State, and that is a skill that fits right in with the Suns' scheme.
"Warren won't be the best overall NBA player from this class, but he might be the best pure scorer, and in my opinion he was the best overall rookie in Las Vegas."
