You live in Nashville. If I lived in Nashville I probably would have jumped on it too. If I were growing up in Tennessee now, I'd probably grow up a Titans fan. I certainly don't begrudge anybody rooting for them. But there's only one team that plays football in Tennessee that I give a crap about, and there's no question that the the pro team in Nashville is one of the reasons why they've had trouble filling the stadium.
As I said, I know three people in Nashville, one of them my brother-in-law, all with the same story. Longtime UT season ticket holders. Enthusiastically jumped on the Titans when they showed up. Went to both for a few years; eventually let the UT tickets lapse because the weekends were too much. None of them bailed because the team got bad. They bailed because they couldn't do both.
As I said, I don't blame anybody in Nashville. But personally, I see no reason to root for that team at all.
