Who cares really? When the seniors came back out and if they asked the crowd to come down with them, I bet everyone would have.
I don't get my undies in a bunch if a teams' fans storm the field or not. I don't see it as disrespectful, classless, or anything so long as no property gets damaged (ie: tearing down field goals, ripping up the field, etc etc).
If fans want to celebrate with their team, who am I to judge? Sure there is the "act like you've been there before" elitist attitude but people are human. Emotions run wild. People do crazy things. I often wonder how fragile the UA fanbase is or if we really do think we are better than anyone else on a personal level (which is wrong IMO). What ever happened to the phrase "live a little"?
In a time that this country is in right now, do I really give two wet farts if a teams' fans storm the field? No.
