Did you watch to the end, they destroyed SF 42-13 (who a lot of people think are the next SB winners)? If that's not a sign I don't know what is.
I didn't even watch till the beginning! It was quite late and there was no indication of when the match would start (and it didn't look like it would do anytime soon) so I went to bed. However, it does sound like it was a good game. Good ol' Seattle.
