Let me start by saying I have got this idea from both the NFL and NHL alternate universe threads.
In 1976, the National and American Basketball Association reached a merger agreement, with four ABA teams (San Antonio Spurs, Indiana Pacers, Denver Nuggets, and New York Nets) joining the NBA. However, both the Kentucky Colonels and St Louis Spirits were both told that they would receive a spot in the NBA - but they didn't. What if the NBA did honor their agreement with Kentucky and St Louis, and they added 6 new teams into the league? I will not be doing a yearly standings, but will state the champions. I present to you an alternate universe. (My phone is almost dead, so I won't post any designs now)
