I guess there was that last Sonics season in Seattle. It wasn't OFFICIAL, but their lease was up and everyone knew Bennett had no intention of keeping that team in Seattle.

OKC already had an arena, so it's not quite the same.

I agree with you, a 2015 season in St Louis would be weird as hell if they actually announce the move between now and then. But it's already too late to play 2015 in LA.
