Nike's biggest basketball star noticed.
Cleveland Cavaliers superstar LeBron James, who watched portions of the game in person, took to Instagram to offer a shoutout to the 19-year-old, posting a video of Ball wearing the kicks and a caption consisting of a familiar three-word phrase:
"Just. Do. It."
What Ball did was earn a double-double by scoring a game-high 36 points and notching 11 assists in his team's 103-102 victory.
