I am a big fan of the San Antonio Spurs.  They play in the Western Confrence of the NBA
I love watching NBA!  How old is that team?
They actually came from the old ABA and moved over to the NBA in 1976 after the merger.
What is the ABA?  I am unfamiliar with that term.
The ABA was the AMerican Basketball Association.  It began in 1967 to challenge the NBA.
