You'd be wrong. The celebration is much better when you beat a top-5 team in your stadium.
I was a junior when we upset #3 Miami in 2005. Since it was at Miami, I was in my dorm room talking to my friends about the game.
After we won, we were all like, "Wait, did that just happen? So, uh, now what?" I drove around to see if anything was happening, and there was nothing.
Contrast that to when we upset Auburn in 2003 (I think they were around 17th at the time, having lost to USC the week before (and we had lost @BYU ourselves)) and we rushed the field, tore down the goalposts, and carried Reggie Ball off the field. (Chew on
that for a minute.) I followed the goalposts up Techwood and eventually to the President's house. On the way there, I saw a dude walk out of a frat house with a wheeled welding kit. I was a freshman at my first college football game ever.
Of course, later my freshman year some chaos did break out when Will Bynum did his thing against Oklahoma State in the NCAA Tournament. But for that, it helped that everyone was watching in various groups around campus and whatnot.
