The San Antonio Spurs are still dealing with a coronavirus outbreak. Their state is reeling from the aftereffects of a deadly icy blast that has affected millions of Texans. One of their best players is mourning the death of a parent. Given all that, basketball seems secondary to the Spurs right now. But they were back at work, holding a full-fledged practice for the first time since it was revealed last week that at least four players tested positive for COVID-19. They will be without at least six players when they return to the court Wednesday for a game at Oklahoma City.
