I think SB49 tends to bother newer fans more then old timers.
After suffering for decades of gut-wrenching losses through the 1970's-2000's, the dominance of the SB48 win washed away any worries I would never see a Seahawks SB victory. My own personal journey as a Seahawks fan over the years is fulfilled. The rest is icing on the cake.
And here is the thing about SB49... Literally everyone on the planet thinks, the Seahawks "should have won". Even Patriot's fans will tell your this... off the record. While it won't show in the record book, in reality SB49 kinda comes with an asterisk. Listen to whenever SB49 is brought up by any sports pundits/announcers/fans. They say, "Pete Carroll and the Seahawks went to back to back SB's, won one, should'a been two."
I have come to grips with the fact that SB49 has gone down in history as a great game, that ended on a great play by an obscure player, due to a questionable play call. It won't be forgotten, but neither will the SB48 win. Those two SB years (along with the NFC championship games) cemented the Hawks into NFL history and lore forever. That can't be denied.
Before Pete Carrol and SB48 the Seahawks were always an afterthought. Seattle never got any respect from other fans or media. As a kid growing up, I would watch NFL highlight videos in the 1980's and 1990's hoping see a clip of the Seahawks. Many times there were none. The Seahawks were just ignored. Like the barley existed. The hawks were just that crappy expansion team out in southern Alaska. If there were any highlights, usually it was Bo Jackson running over the Hawks on Monday night football, or an occasional Steve Largent catch.
Today, thanks to SB48/49 Seahawks highlights are everywhere, people all over the country wear their jerseys, and players and coaches are household names. 12th man flags are waved by fans all over the world. So much has changed with this franchise in the last 10 years... for the better.
I have a hard time feeling "hurt" about anything.
