Many people keep saying it won't make a difference, but I have to disagree with that analogy. Going to Golden State is the easy way out and it will hurt his legacy. Lebron James legacy was not cemented until he came back to Cleveland and led the team to the NBA Championship. Durant is going to a team that has already won a championship. His contribution will not be valued as much because Golden State was already the early favorite to win anyways.
Durant has disappointed a lot of people by his decision, but it will be one he must live with down the road. I think staying in Oklahoma would have been the best move, but only time will tell on that one. Russell Westbrook now becomes the man in OKC and they are still going to be a good team. Durant will be hated forever in OKC, but it was his choice and in my opinion not a wise one.
