I'll grant you that flames aren't necessarily the first thing you think of when you think of the word "titans," but what do you think of? The word "titans" doesn't conjure any specific imagery, the way rams, eagles, falcons, etc. are all one very specific thing. The Titans are in the same boat as the Chargers, Steelers, 49ers, Texans, etc. So, you invent imagery for your team. You create the association yourself. The flameheads are an established tradition in Nashville and it's one that I think should be embraced, rather than replaced.
