I don't see Durant leaving OKC unless he can find a better situation than the one he's currently in. He's not going to go to Boston, Washington (as much as it kills me) or New York and lose in the conference finals to the Cavs every year or go to the Lakers and lose in the second round to the elite teams in the West. He can do that in OKC, make more money and do it outside of the spotlight of living in a big city.
Weirder things have happened but KD just doesn't come across as a guy who's interested in being the big guy in the big city. As for Durant to the Dubs, ehhh. Assuming they can get the chemistry right, they'd be an unstoppable juggernaut. However, getting that chemistry right is incredibly difficult and I don't see them wanting to fuck up an already perfect situation.
As for my Wiz, I hope they continue to suck this year, fire Whitman and Grunfeld, get a decent lottery pick and turn their expiring contracts and young talent in to a big-name free agent. I'll settle for just firing Whitman and Grunfeld though.
