Good post, Cez...
Thing is, not all bandwagoner fans are awful. My wife and daughter are two of them.
Sometimes it's a moment in time, a play, a game, a congregation of fans in one accord that turns one into a fan of a team.
Like you, my dad was a Seahawks fan and it was all because of him that today I am one too. Back in '83, he took me to meet the players (Largent, Warner, Zorn, Krieg, Green etc.) at the airport, after they beat Dan Marino and the Dolphins IN MIAMI. They lost the next week to the Raiders in the AFC Championship, but it didn't matter. I was a fan from that point forward. He wasn't with me last Super Bowl or this one to see the success of this team, but I always get emotional thinking of my dad (he passed away in '08) when something special happens from the team were we formed our bond as father and son growing up.
