What NFL teams do you think have the worst and best fans?

Well for the best fans i really think the Packers have the best fans because they really care for there packers. And im not really sure for the worst fans. But i was watching the Packers vs Falcons game in the playoffs and i like the 4th quarter all there fans just left so im thinkin the falcons dont really have good fans because they didnt even stay to support them even though they were loosing. So who do you think has the worst and best fans?
