Wife is a Cowboys fan so I wind up watching all their games, but I don't feel like trying to become a fan.
Actually, I'm not sure if I can "become" a fan of anything. Seems like it's something that either happens or it doesn't.
I have enjoyed watching Stroud with Houston though, and have found myself, strangely, rooting for him to do well. Maybe I could turn into a Texans fan. But it feels more like the Brees/Manning/etc. thing......I'm just watching players I like, I'm not really rooting for the team, per se. When Brees retired, I had no further desire to watch the Saints, as expected. I never cared about them prior to Brees. Not sure I could make myself care about Texans games if/when Stroud is gone. Actually, he missed some games recently and when I saw that, I just changed the channel.
I guess I'm contented enough to watch a few games here and there as a neutral observer. Not being a fan of any particular team doesn't make it uninteresting.
