Do you really want a team yanked from another fanbase to give you your own? It's the same thing that happened to your Sonics.
It sucks though, really, especially because the Thunder became a legitimate powerhouse team a year or two after leaving Seattle.
Seattle clearly deserves an NBA team again, and I feel like it'll happen in time — it'd just suck if it was a result of another classic franchise (like the Bucks) to be forced out due to arena rules, which was pretty much exactly what happened to you guys.
