But Cuban’s optimism is rooted in science and medicine. “I think we’re coming back,” Cuban said. “I can’t tell you exactly when, but this is purely a science and doctors thing. My attitude always is it’s not about if the glass is half empty or half full, it’s who’s pouring the water. In this particular case, it’s the scientists pouring the water. All I know from all the science and everything that I’m reading, I think we’re making enough advances that several of them will come through so we can start planning what a comeback would look like. I’m a big believer in American exceptionalism, and everything I’m starting to hear in terms of the science is coming along and the medical advances that we’re making to fight this thing makes me very positive. If I had to bet, and this is more a guess than a bet, I’d say early June is when you see teams start to take the field and maybe play games just for television.”
