I committed to the franchise when I was ten. Committed to my wife when I was 27. Both are marriages. I am not divorcing either of them. Plus, I have told my kids their entire lives my tombstone will read 'Cowboy Fan For Life' or I would haunt them forever.
All that said, my wife is a Denver Broncos John Elway/Peyton Manning fan. She may have other plans for the two of us (she's sneaky!)
On a serious note, I have always thought individual opinion is usually dictated by personal concepts of team and franchise. Some people identify primarily with players, coaches and the uniform. Other people, like myself, attach our fanship mainly with a franchise. Sure. Winning is easy and losing is hard but neither are determining factors for fanship to those who align their allegiance with the overall entity itself.
It is also the reason why Jerry Jones & Company never get under my skin to the degree that it does for others. Yes. Jerry Jones is the Dallas Cowboys. However, he is only the current owner slash self-appointed president slash embedded like a tick general manager. Jones is not and has never been the single soul of this franchise. The franchise is the combination of countless players, coaches, fans, failures, championships and bountiful history that began in 1960.
That is what the Dallas Cowboys means to me. That is the ground where my fandom has always stood and will continue to stand without fail.
