LOS ANGELES — Slouched deep into one corner of a velvety couch in his spare bedroom, bare feet propped on a matching ottoman, Josiah Johnson is searching for his big moment, like a point guard probing a defense.
His gameday attire includes a faded Seattle SuperSonics T-shirt. His laptop rests comfortably on his thighs, iPhone clutched in his right hand. His more than 232,000 Twitter followers are waiting.
The possibilities unfurl on a large flat-screen television in the opener of the NBA's Eastern Conference finals. Maybe he'll tweet about a celebrity in the crowd doing something funny. If Jayson Tatum continues to pile up points, maybe the Boston Celtics scorer also will star on Johnson's timeline.
