With his impressive combination of size and athleticism, 7-foot-1 Timofey Mozgov has worked hard to establish himself as one of the league's top defensive centers. The Cavaliers found that out firsthand when he tied a career high with five blocked shots in his 14th game in a Cleveland uniform upon his trade from Denver in January 2015. He also had two games in which he blocked four shots that month. He tied that number again in the postseason as the Russian native turned back five shot attempts in Game 2 of the opening-round sweep against the Celtics. He also had 16 points on 7 of 11 shooting. One of the best defensive big men around, Mozgov is seen here blocking a layup attempt by Bulls guard Aaron Brooks. Mozgov has signed this Block 8" x 10" image in silver paint pen. His signature is deemed authentic by virtue of Upper Deck Authenticated's Five Step Process.
