IT'S A RECENT Friday night in downtown Pittsburgh, JuJu Smith-Schuster sits in a mid-sized hotel conference room, having just completed his promotional duties for a "Call of Duty" livestream. In one corner is a table of picked over and forgotten food and drinks on ice. When Smith-Schuster walks in, wearing a black tee and black joggers and black Yeezy Boost 350s, he asks for a Shirley Temple, "extra cherry." After playing for more than an hour and then conducting an interview, Smith-Schuster and a few streamers invited for the event are back on the sticks, their eyes darting back and forth across the screen.
