You can't really knock anyone for being bandwagon when you are a packer fan who has never lived in Green Bay 
I define a bandwagon fan as someone that that becomes a loud overzealous fan when their team become good after never caring before. Every great team has them so they are a sign of success. The Seahawks just happen to be a recent/current example. The year they lost the playoff game in Atlanta the fan base started rapidly expanding. Every Friday/Monday during the next season I rode the foot ferry that was full of Seahawks gear and people talking about the game. It just kept getting bigger every week until they won the SB. For the most part it continued the next year, but the level of excitement had dropped off. After losing the SB last year and losing the first two games of this season you couldn't tell if the season had started or not based on the ferry ride. There was almost no Seahawks gear and no football talk. Keep in mind it's pretty much the same people year in and year out (we're a bunch of lemmings). Things are still pretty quiet. Meanwhile, the real fans are still being real fans.
My favorite Seahawk "fan" ever was a lady that I overheard telling someone in the grocery store that she thought the SB would be Seattle and Green Bay...clearly a lifelong football fan! It was all I could do to keep walking, partly because I wanted to say something and partly because I wanted to fall down laughing.
I started rooting for the Packers in the pre-Favre era when they were not a great team. The local Broncos were a much better team at the time. I had a friend that was a Bronco/Viking/49er fan depending on which team was doing the best, drove me crazy...
Back to the regularly scheduled programming...
