Fair enough. OKC probably isn't as good as they were now while we are better than the '11 team. I'm still unconvinced that the Spurs can win more than a game in OKC.
The Thunders defense has slipped recently and several players in their rotation are liabilities on that end (Butler and Fisher, who are used to close out game) When they get Perkins and Sef. back there defense should improve but their offense may slip a bit. Perkins ORtg is just 82/100, While he does a good job of guarding Duncan in the post, his lack of offense allows for other teams to ignore him.
Sef. has regressed as a shooter (33% 3pt)and Butler is hitting only 35% of his 5 3pt attempts. Thats 2 rotation player who can't shoot consistently from deep.
As for the Spurs, Diaw can draw Ibaka several feet further out of the paint. The Spurs offense is more diverse with less reliance on Parker. The series would be a toss up if Spurs have home court and probably 40/60 if OKC has home court.
