OKC adds James Harden and BJ Mullens, which rounds out a starting five that would feature Westbrook at the 1, Harden at 2, Durant and Green at 3/4 and prolly Mullens at 5. If nothing else, that is a team that can win some games. They are probably not at a contending level yet, but if Harden develops into a quasi B-Roy type of guy as he has been projected to become, it would be interesting to see whether he and durant will coexist. Don't know if Mullens sticks, so that will be interesting to see as well.
Don't know if OKC has now improved its roster enough to challenge for the 9th spot in the WC, let alone a playoff seed, but the NW division almost certainly got tougher today.
