The dad who called out his son during a few NBA games for his bad grades is speaking out. The father, Tommy, attended a series of basketball games across the country and held up signs with messages for his son. One of the signs, which Tommy, who asked for his last name not to be used, was lifted at Friday's Cleveland Cavaliers/Charlotte Hornets game: "Thomas get your grades back up and next time you'll be here. Love, dad." The sign even had a crying emoji and the Cavs logo.
