McCloskey is an effective off-ball player who moves well without the basketball and does a nice job coming off pin-down screens to create scoring opportunities. He is a legitimate threat from beyond the three-point line and can make defenses pay when given space. Defensively, he does a good job walling up around the basket and contesting shots in the paint. McCloskey impacts the game in a variety of ways, consistently stuffing the stat sheet with his all-around play. His versatility, effort, and willingness to do the little things make him a valuable glue guy who contributes to winning basketball.
