So much negativity. The word fan is loosely used around here. Are we only fans when they win? Do we only support our kids if they win that soccer game? I understand that some people aren't really that big of football fans, and only a fan of the team. However, I would assume that those folks don't usually participate in forums if they are casual fans.
Lambeau is an amazing place to watch football. Two of my favorite games to watch at Lambeau were losses: the 2007 championship loss to NY and a loss to Seattle during the Ray Rhodes era. Both were fun for their own reasons, but it is just fun to be at Lambeau and to watch football. It was hard to go to games in the 80s but still a treat.
I've supported a terrible Minnesota Gopher football team for years as a season ticket holder despite watching them lose consistently. I've also made the trek to Camp Randall almost every year to see them lose. I also used to have season tickets to the Vikings back when they were terrible. I don't think that this makes me anything special. It just means that I enjoy watching football games, and it doesn't alter my experience so dramatically if my team wins or loses.
A fan, IMO, is a person who follows the Pack and wants the team to win. If elements of the organization aren't performing well, we become fans with negativity. The people I think you're referring to are those that would change allegiance, based on the record and performance. The fact that I and the others are here, bemoaning the current situation confirms that we are, indeed, Packer fans. I *****ed for 2 1/2 decades after SBII, but I never turned to the Steelers, Cowboys, 49ers, or Patriots as my team.
Your soccer comment is also one I use often, in a manner 180 degrees out from yours. I would support my grandkid's teams and attend their games because he would know and care if I didn't. There is nobody in the whole Packers organization who knows or cares that I'm alive, much less whether I unconditionally support their millionaires.
Finally, many of us really do find the results of a game to affect our appreciation of it. I'd never even considered a position as stated in your last sentence, but if that's how you view sports, more power to you. Just please don't try to define other people's 'fandom' by it.
