Of course I don't take attendance, but I've been going to games since 1972, and I went there for 7 years. I had a streak of 30+ years without missing a home game that I ditched during the Weis debacle. The student section isn't packed the way it used to be, but the composition of the student body has changed.
Nobody blames current students - there was a malaise during the Faust years, too. Not as extended, but it was there.
We had night games. We had fewer games. We had better teams to watch.
In conclusion, the students who go are great. There just aren't as many.
