Why did the 1972 Dolphins play the AFC title game AT Pittsburgh? Was there no HFA back then? How did they determine where the game would be played? I was watching the America's Game on the 72 Dolphins last night, and they showed the playoffs. Miami winning, and then Pittsburgh beating Oakland (in Pittsburgh) to setup the AFCCG. Pittsburgh was not undefeated as Miami was, so why was the game in Pittsburgh? Pardon my ignorance, I was not born until 1980.
