if teams put an overhead camera on the opposing teams timeouts and mic'd up the bench and there was an assistant coach on the home team listening in real time and then telling his team the plays? Then imagine that team winning the NBA finals somehow anticipating every offensive play and everything the visiting team did. Then imagine it's all brought to light with video evidence.
That's what happened here.
But if Lebron looks over at the Warrior bench and sees Steve Kerr pointing to Steph Curry that's Kerr's bad and he tipped the play. That's fine.
