Season 2: 1973-74 Season
Expansion/Relocation: Ottawa Nationals moved to become the Toronto Toros & Philadelphia Blazers moved west to Vancouver keeping the Blazers' nickname.
Side Note: I found that in the playoffs some teams played 1, 3, 5, 7 & 8 games, it was because the game switched the quarterfinals from 7 to 1 game.
