No, it's not. According to Merriam Webster (jeezus, I can't believe I have to cite the freaking dictionary on this) the definition of "tradition" that best fits this situation is "a mode of thought or behavior followed by a people continuously from generation to generation; a custom or usage." The reference to the 29-29 Yale-Harvard tie proves my point perfectly. That was one of the greatest games in college football history, in a heated rivalry, and I think it also decided an Ivy League title. Running onto the field was not a "tradition", it was a spontaneous act brought about by the amazing circumstances the crowd witnessed. If they did it every game, or every year, you might have a point. But as it is, you don't. Field-charging isn't any more a tradition in college football than fan fistfights are a tradition at NBA games. No, it's not. I've seen plenty of cases where field-storming was not allowed, and the fans complied. No, injuries in this sort of thing are not rare, much less "rare" with a number of verys in front of it. Any time you have a large number of uncontrolled, fired-up individuals, the potential for trouble and injury is large. Don't make me post a list. This is like saying, "either accept graffiti, or don't build walls." Give me a break. You start with the assumption that you're going to do whatever you feel like doing, and if the rightful owners of the property that gets damaged in the process don't like it, it's some kind of personality flaw on their part. This is childish, self-centered thinking. I agree. When the stadium policy says stay off the field, you should stay off the field.
