I don't really dispute that, I've been aware of their strong fanbase even as they've had to endure some terrible teams for decades. there is a major influx of bandwagon fans on top of it though. I'm sorry for accusing them all of being bandwagon fans bro
Every winning team has bandwagon fans. I am willing to bet there are some 'fans' out there with Urlacher jerseys deep in their closets. I'm sure they are right next to their Elway jerseys and their McNabb jerseys. But there are a lot of true fans up here. Most of my friends these days are SeaHawks fans. I can't say that I am a fan, to me being a fan means sticking with your team, even if you aren't living there anymore but I don't cheer against them. I certainly was happy to see them win against the Packers.
Until recently the Hawks had the reputation of being a team that could only win at Quest. If you remember the teams of the early 2000s that was their entire MO, great at home, mediocre at best on the road. This was entirely because of the fanbase which could really get Quest field rocking. This was entirely because of the fanbase, the team fed off of them and played better because of that fanbase. Lets face it, there isn't much else up here to cheer about sports wise. The city lost it's basketball team, the Mariners haven't been relevant in 15 years and there has never been an NHL team here. For the most part it has been the University of Washington and the SeaHawks.
Now if the Mariners start winning I will be all over the bandwagon fans here because when it comes to baseball a large number of them are bandwagon fans. In the 90s they loved this team but don't seem to give to snots about them now. And they are pretty good. If the Cubs had a field like Safeco in Chicago it would be sold out every game. Even when they were in the division race it was hard to get the place filled up.
