Since I am a product of the North Carolina University system, I will root for any North Carolina college football team against anyone else. How does football system affects the hobby, me personally football season gives me a good reason to ask providers if they have a cheer outfit in their closet.

University of South Carolina Gamecocks!  
(Florida State would a be a second.)  

No True Loyal teams in the NFL. Anyone but Dallas?  

As for the hobby, it doesn't affect me Personally at all. While I love Football, a Beautiful Lady will come first every time.  
DVR it or check the score another time. I'm not passing a Date for Football...
