Earl Clark, 23, played sparingly with Orlando, appearing in 33 games.

Van Gundy says he has a specific role for Clark if he can meet the challenge: designated defender.

"We want Earl to guard the 3s and 4s who are primary scorers, seeing if he can guard Kevin Durant, Paul Pierce, Joe Johnson, Dirk Nowitzki … the bigger wings and the 4s," Van Gundy said. "That's where I see Earl coming in and getting his minutes."
