I like certain teams more than others but wouldn't say I root for them.
I used to be able to say that about the Texans, but Texans fans - basically Aggie fans for the pros - turned me against that one pretty quickly.
I like the Colts and Broncos more than most teams over there in the AFC, and when they're not playing us, I have a little bit of an affinity for the Bears and Rams as well. I don't have an explanation for any of this, although it's fair to say that I'll root for most midwestern teams over the coasts.
Pretty idle level of interest in any case, fairly similar to my preference for Contadina tomato paste over Hunt's.
