Recap
The 1949–50 NBA season was the inaugural season of the National Basketball Association, which was created in 1949 by merger of the 3-year-old BAA and 12-year-old NBL. The postseason tournament (the 1950 NBA Playoffs) at its conclusion, ended with the Minneapolis Lakers winning the NBA Championship, beating the Syracuse Nationals 4 games to 2 in the NBA Finals.
Commonly 1949–50 is counted as the fourth NBA season. It recognizes the three BAA seasons (1946–47, 1947–48 and 1948–49) as part of its own history, sometimes without comment.
I sincerely appreciate the research work, and the information being shared. It is important and interesting history.
