Shooting Guard. Cleveland Cavaliers. AUSTIN CARR. SG. You could make a serious case for World B. Free as the best shooting guard in Cavaliers history, but Mr. Cleveland can’t be topped. Austin Carr is probably, next to LeBron James, the greatest Cavaliers player ever, both in what he did on the court and what he did off it. He’s synonymous with Cleveland, and the Cavaliers are indebted to him for their entire existence. Putting him in this lineup not only pleases fans, but puts his talents on full display among all-time greats.
