I'm worried Sonics might win this series

Allright, I think I mentioned earlier that I arbitrarilly decided to become a SuperSonics fan. However, they are now tied with the Spurs at two games a piece, and have a good chance of getting into the Western Conference finals. This makes me think, what if the Spurs make it to the championship, or even win it? Then if I start cheering for them next year, I'll look like an iddiot. I'll be that guy who just cheers for whoever is good right now. I don't want to be that guy, I want to be the guy who likes the Sonics for some unknown reason. So while of chorse I'm cheering for the Sonics while I watch them, part of me wants them to lose. It's really a very strange situation.
