I know there was a time where I've gotten livid, steam-coming-from-ears, mindless angry over the result of a football game. Badge can attest to it, I've been on the phone with him while in that state.
Some people get that angry and lash out swinging. Others realize that it's not good and gain some perspective.
Also, the amount of problem-level drinking at NFL games puts even the booziest college stadiums (cough cough Camp Randall) to shame. I went to the Vikings game at the New Brickhouse the week after the Metrodome roof fell in. No sooner than I arrived than I saw 3 cops hauling off a man who was HAMMERED. While doing so, the man projectile vomited all over the concourse. Everyone just walked right through it.
