I really don't understand how people think OKC has a chance against Memphis. Granted, the Grizzlies' transition D is not amazing, but that's their only weakness. And the only reason they aren't great at getting back is because they crash the offensive glass, which they have done well against the Thunder in the regular season meetings.
Now with Westbrook out, obviously the main source of fast-breaking offense goes with him.
As I read somewhere, Westbrook being out vindicates him a bit. People love to get on him about his bad shot selection and decision making, but look how bad they are without him.
