I don't watch College football really, but when I do, I am a UT Volunteer supporter since I went there and all. I saw enough college ball in the band at UT though so I don't watch it at home.
I am a rabid NFL watcher. As a matter of fact, in my family we flip roles. My husband likes football but will only sit through 'big games' so mostly on Sunday he piddles around the house or entertains our daughter while I watch football. He also usually cooks on Sundays.

One might say that I have him trained well. I just say that he understands my football obsession and loves me.
I grew up in the Metro DC area with a Mom who is a rabid Redskins fan. I was too until a fateful Redskins/Cowboys game when I was about 6 years old and I realized that if I cheered for the Cowboys it drove my Mom nuts. Of course, it only being football, it was a nice way to rebel against her without risking any actual trouble. Thus, a Cowboys fan was born.

My husband's family was also Cowboys fans, so he routes for them as well.
I am still a Redskins fan as well though, and I also cheer for the Denver Broncos third.
Today after Church, we will do what we've done the past few years when the Cowboys and Redskins play. Jeff and I wear Cowboys outfits and Katie wears her Redskins jersey. We usually make a point of going out to lunch or grocery shopping this way just because the comments we get are funny.

Katie has jerseys from the Redskins, Cowboys and Broncos, and we have baby outfits from all three for our son (who will be born this coming Wednesday) to do the same. We just rotate them as needed.
Today Jeff will cheer for the Cowboys and Katie and I will cheer for a good game.
Oh yeah, and I am also on the list for Denver Broncos season tickets. My husband is from Colorado Springs (but oddly, isn't a Broncos fan like me, and I was one before I met him) and we plan to move to the Denver/Co Springs area in the next year or so. We only have 12 to 15 years before our names MIGHT come up for tickets, though. *laugh*
