From an article on the video:
Of course, LaVar Ball was in on the joke the whole thing. A press release from Foot Locker confirms that Mr. Ball knew all about his son’s deadpan hi-jinks. Imagine how awkward things would be if big daddy Ball was against his son poking fun at him on the worldwide web. Ball won’t have any issue when this commercial airs during the NBA Draft in eight days. Or will he?
Lonzo Ball said in the Foot Locker press releases that, “My dad and I both love the humor of the spot and I’m glad I got to have a little fun around the topic before going to the league.”
