I don't know. Between the Cavs winning the championship a couple of years ago and the play of the Indians, being a Cleveland fan isn't that bad right now. True even though the Browns still suck.
Raiders (over a decade of suckage until last year), Braves (once prominent now relegated to the cellar), and Devils (see Braves). The Noles title in 2013 was one of my teams championship since the Devils in 2003.
Born and raised in Buffalo. 20+ years out, it's still what I think of as home, I just live in Atlanta.
In the last couple years, my 13-year old son has taken up adopting the Buffalo teams. Even had me take him out to see the AAA Bisons when they played the Gwinnett Braves. I'm like..."What? I was born to it...you don't have to choose this life."
I mean, he's lived his whole life in Atlanta...if you don't saddle up with Atlanta teams, why pick one of the few more loser-ish sports towns than Atlanta?
