IMHO, the thing that is important to remember is this.
There are many different types of fans.
It's just the nature of the beast.
There are fans that root for a team no matter what, i.e. Players, coaches, win loss record.
There are fans that root for a team because of a certain player, if that player moves they move.
There are fans that root for a team because they are winning and its "cool".
There are other reasons that people are fans as well.
Some people are Seahawk fans for no other reason than P.A. is the owner, or P.C. is the coach.
I've been a Seahawk fan since the day my mother and I heard the news that Washington was getting an NFL team (we didn't even know yet, what the team would be named).
My reasons for being a Seahawk fan may not be the same as the guy sitting next to me, but he is a Seahawks fan, and I'm no better "fan" than he is.
YES, they are still our boys and IMHO the more "fans" the better, and anybody that worries about why somebody is a "fan", is wasting their time, worrying.
