LOL!!
That goes back YEARS!!! When I was about 8 or 9 or so, I remember the SBs on TV. The Dallas/Pittsburgh games...Anyways, both my mother(especially her) and my father had a loathing for Dallas...Well, you know how impressionable kids are..Anyways, we always rooted for Pittsburgh...
Then we moved to Washington when I was about 9(almost 10)..It was 1977 when I fell in love with the Seahawks(thanks to Zorn and Largent)..Been hooked ever since despite moving to Michigan in 1984(Became a bit UM fan though, hence why I love Brady)..
Anyways, through the years I have had many bad experiences with Dallas fans...There are maybe 1 out of 10 that I have met or corresponded with that had any sense..
And it just bothers me that the are hailed "America's Team".
But really, it just the experience with the fan base as a whole.
IMO, the coolest fans from other teams(yes, minus a few bad apples; who doesn't have them?) are Carolina, Cleveland, New England, and Tampa.
Of course, those are just my experiences.
It could be different for someone else.
Sorry if this explanation is too long. LOL!!
