Actually it was toned down when Marino started playing. He did bring some life back into things, but he also had a lot of Jets fans going to games just to see him play. They would wear Miami Jerseys, and if the team was playing the Jets, and the Jets won, you would see them taking them off, wearing Jets Jersey's underneath. They would also start cheers when Miami was on offense at the LOS. That stuff caught on too, because to this day some Miami fans still do it.
There was nothing louder than the early 70's during the terrible towel/Super Bowl days. It was absolutely deafening.
