For younger people and veterans who want to remember, here is the original look at the NBA and the playoff system, which was not really logical. Each team played 72 games for a total of 288 games the entire season.
New York Knickerbockers
Philadelphia Warriors-now the Golden State Warriors
Syracuse Nationals-now the Philadelphia 76ers.
Fort Wayne Pistons-now the Detroit Pistons
Minneapolis Lakers-now the Los Angeles Lakers
Rochester Royals-this team became the Cincinnati Royals, the Kansas City Kings, and now from Sacramento.
St. Louis Hawks-now the Atlanta Hawks
Playoff Systems-All the regular season did was eliminate the last place team in each division
First Set-the second and third place teams in each division played a best of three series. I assume the first two were in the city of the second place team.
Second Set-The first place team in each division played a best of five series with the above winners. I assume the first two were in the city of the first place team.
Final-The winners of second sets in each division played a best of seven series.
Simpler time but a complicated playoff series.
