I just researched the top 10 rumored OKC NBA names and have found that only 1 is registered with the NBA's Domain Name registrar.
Thunderbirds
Also, Clay Bennett is known for being a "Staunch" Republican...he probably had this name in mind for some time now. I mean you can't tell me he hasn't found something he likes in the last 5 years he has been dreaming about this moment.
So what does being an Ultra-Conservative have to do with it?

And no, no name has been registered by the NBA's attorney of record, Anil V. George, yet. But if someone were to intercept their creative ambitions, they could easily prove the person was acting in "Bad "Faith".
Oklahoma City Thunderbirds...no not the 80's kids show the Thundercats, thats a name that they would have trouble registering.
