This brawl in the stands between 49ers and Cardinals fans in Phoenix is extremely ugly. To make matters worse, members of stadium security got dragged into it. They didn't choose to get drunk and hurl insults, they were just there to work. Alcohol combined with heated emotions and tribalism is never a good mix. Seriously how about behaving like NFL fans and less like NFL players?

Here's a quick rule of thumb to being a good fan:

Are you behaving like a human being who is a well-adjusted member of society?

- If YES: Congratulations, you're ready to watch the game.

- If NO: Don't go to football games.

UPDATE: Darnell Dockett weighs in:
