When does Untitled American Basketball Association docuseries return?

The American Basketball Association (ABA) was a major professional basketball major league that operated for nine seasons from 1967 to 1976. The ABA operated in direct competition with the more established National Basketball Association throughout its existence. George Mikan came up with the idea for the three-point shot to go along with a 30-second shot-clock; echoing the NHL, the league named a Most Valuable Player for the entire postseason rather than for just the Finals. The Pacers would win the most championships in league history, winning three with stars such as Mel Daniels, the first player with multiple MVP awards.
