Long time lurker here, but honestly the only way to get rid of the sting of losing that perfect superbowl record mark is to win two more and be in sole possession of the most number of Superbowl championships. Until then, this loss is always going to be a blemish on our franchise. I know that's a little dramatic, but the fans, players (past and present) and the management of this organization all took great pride in our history in Superbowl games.
I'm just hoping the team right now doesn't feel this sense of defeat and this "it's all over with attitude" that the fans currently feel. For a lot of the faithful, it's been 17 years of being emotionally vested into this franchise to get to our next Superbowl and to come within 5 yards of that is just utterly defeating and overwhelming. So I can definitely empathize with our fan base who are "overreacting" this wasn't just two years of hard work commencing into a tough defeat, this was almost two decades of moderate success and bitter dissapointment ending in one last loss on the biggest stage and the game was completely in our hands to win.
