Please prove me wrong!

The following statement is something I first said probably 10 or so years ago. I made this statement originally as a comment to get a rise out of local sports fans, but as time has gone by I feel it is actually a pretty strong comment. " No professional team from the Pacific Northweast will win a National championship as long as I'm alive. This includes the Mariners, Seahawks, Supersonics, Trail Blazers, The University of Oregons football team and Oregon State University's Football team."
I decided to write this now as the Seahawks have the best chance of proving me wrong as they ever have had. It's a statement I've always stood by and at the same time have wished to be proved wrong about. The following reasons are what I based this on. Having been to and watched many of these teams, they all seem to have a lot in common. First and foremost, their fans seem to route them on, but at the same time they don't seem to believe in them. They keep waiting for that proverbial letdown and then they pounce all over it with a "I knew it would happen in unison." Another big problem is consistant letdown. It seems as soon as they have proved they are a good team they fall apart. Sometimes it is a major letdown that ruins the rest of the season, others it does just enough damage to keep them from that one necessary win. The ability to self collapse is the major theme holding any of these teams from becoming true champions. While I wish the Seahawks good luck from here on out, I'm pretty confident they will fall apart come playoff time.
p.s. Not fair to add something after the fact, but The U of O proved exactly what I was talking about yesterday at the Holiday Bowl in San Diego.
