I'll have to look at these when I get home because the links are to banned web sites at my work, but I can comment on two of the student groups you cite...
In 2002 at PSU, we were assaulted (physically), spit on, beer spilled on, etc by students before, during, and after the game. What's more, we had to look at "F**K the Huskers" t-shirts everywhere, since student reps were handing them out at the gate. No, the letters were not changed around. Joe Pa ended up issuing an apology on behalf of the university the week after the game, and the campus promised a "crack down" (whatever that means). I doubt if I'll ever go back if we schedule them again.
The Terp basketball fans are NOT looked upon as a shining example of student behavior here in the state. The school has banned Gary Glitter's "Rock & Roll Part II" from being played at the games because of the way they added offensive lyrics. Of course, we all knew it wouldn't do any good, because they continue to sing the song anyway - without music. Yes, they are fanatically rowdy, especially when Duke comes to town, but their actions are not viewed in a positive way.
I can't comment on our students' enthusiasm, or lack thereof. I can only say that the two examples above should not be used as a benchmark of what a "good" student section is.
