You've probably seen the clip. It's the one in which LeBron James is shouting at Kyrie Irving on the bench in an overtime timeout while forcefully poking the shoulder of the point guard seated two chairs away. Instead of facing James, Irving looks straight ahead and refuses to make eye contact. James gives him an earful.
As James seems to wrap up his speech to the unengaged audience of one, Irving looks the other way and smirks.
Irving was no child, even though he was seemingly treated like one in that moment.
