You do have a right as a fan to feel any way you want. As a fan of this team "almost since inception" frustration has been prevalent.
11 other NFL teams fans are in the same boat.
You cite the Superbowl years and its frustration. The thing the separates me from you is, that group of owners, coaches and players have nothing
to do with the current cast. The current group of men (and women) who daily represent my hometown team have yet to realize
their final ultimate outcome. So, until that unfolds, I prefer to look toward the possibility of a championship and see no correlation
to past teams.
I guess after all the analysis, discussions, arguments and expectations are over, I'll always be a "homer".
