This doesn't really answer the question, but it sort of does. We've had season tickets since 1990, so that's all I have to draw from. For my money, the 1990's have not been matched for noise and excitement since, although I feel there's plenty of potential going forward, especially with the congregation having gotten a little younger over the past couple years.
I have never seen a crowd so jacked up as for the home opener against Wisconsin on January 12, 1994. It was the year when Arriel McDonald and Randy Carter were seniors, and Lenard, Orr and Walton were juniors. There were extremely high hopes for the team. They had won at Northwestern to start the conference schedule. Walking there along 4th Street, fans were spontaneously chanting, "Here we go, Gophers, here we go" on their way to the arena. I've never heard that kind of thing on the street before or since. The Gophers started slow, and the Badgers with Tracy Webster and Michael Finley started hot, but after the first TV timeout it was all Gophers. Once the home team started to catch up and go ahead, the place was pandemonium. 90-53 was the final score. The 106-56 win over the Hoosiers occurred later that season, but it directly followed a double-digit loss to MSU on the road, and by that time the Gophs had lost 6 conference games, and the bloom was off the rose just a little. The Indiana game was loud and crazy, but I remember much more energy in the building for the UW game.
