The Charlotte Hornets only have three nationally televised games, which is maybe not the most surprising thing in the world. They won 19 games last year, so it's honestly a little bit generous to even have that many.
The Washington Wizards are the only team with fewer national TV outings, and it's not hard to see why these teams aren't being put on the national schedule much. They've been bad, and NBA fans generally don't want to watch them.
However, the Hornets have often been bad and fun to watch. LaMelo Ball plays a big role in that, because he might literally do something unprecedented every time he touches the ball.
