A Mark Cuban and Lil Wayne feud is one of the main storylines of the NBA playoffs? That seems to be the case as the Mavs owner and famous rapper have exchanged NSFW blows with one another on social media. Cuban’s dog in the fight is that he is obviously the owner of the Dallas Mavericks. However, Lil Wayne was cheering for the Suns and is a friend of Chris Paul. Lil Wayne had previously called out Mavs star Luka Doncic during the Suns and Mavs series.
