You don't allow them to pass a goal post to the top of the stadium and drop it over the side. You treat the fans like citizens, which means they're subject to laws. You don't look the other way. Don't tell me it can't be done. It is done at Florida.
Police rim the field instead of drunken students.
Even in 1997, when Florida won an emotional game against Florida State and the head ball coach was waving the fans down, they didn't come. Because the first guy over the top was laid out flat on his stomach and cuffed. It's the same at other stadiums around the country, at Nebraska and Colorado for example. Hey, spare me the e-mails talking about how I'm a grumpy old man. It's about ending the madness before someone gets really hurt.
