VIDEO: Spurs get creative trying to guard 7-foot-3 Marjanovic

There aren't many people in the world who are taller than San Antonio Spurs center Boban Marjanovic.

The 7-foot-3 Serbian ranks as the league's tallest active player, and the 13th-tallest in NBA history, which makes the task of checking him in practice rather difficult.

And so, the Spurs have taken to guarding their giant by having an assistant coach hold an oar above his head. No, seriously.

Tim Duncan is the Spurs' second-tallest player at 6-foot-11, and he can likely hold his own against Marjanovic, but the 39-year-old has (metaphorically) bigger fish to fry than wearing out his ancient body in practice by guarding a walking hulk.
