Were you a fan of the Sonics before they left Seattle and moved to OKC? The Sonics were my first team when I first saw them in the Finals vs. the Bulls.
Always liked The Glove's game but i used to go for the Suns before OKC. Kerr killed that team for me when he started trading away all the defense and my favourite players (Diaw, Bell, Marion etc) and i basically just got fed up with it all.
Sounds a bit petty when i say it like that but NBA wasn't on tv here for years so i was kind of left being a fan on paper only if that makes sense. Bit hard to be much of a die hard fan when you can't watch any of the games.
I started supporting OKC just before their 23 win season a couple of years ago (so hopefully i don't qualify as a bandwagon jumper haha) and the NBA started up on tv here again last season. I still hold a soft spot for the Suns but i'm definitely a Thunder supporter, especially after watching that finals series against the Lakers!
