I read this article, and was waiting for someone to start a thread on it. I'd be very curious as to how they're any kind of front runner. The salary cap still exists. They could release Thompson and Livingston, who are only partially guaranteed, let all their free agents walk, dump Bogut's contract, and still not have enough room to offer a max contract to Durant. A sign-and-trade is difficult as well, because a) they don't have much in the way of draft picks to offer (late 1st rounders several years into the future are only so interesting), and b) the most logical trade involves Harrison Barnes going to OKC in return. Since he's a free agent in his own right, you can't just snap your fingers and make t happen.
They can't be the front-runner just because they want to be.
