I don't think "experience" matters too much. Chicago has zero experience and they might beat Miami, a team that has two superstars who have been to the Finals.
What are the Mavs going to do about Westbrook? The two PG's they have played against this postseason are Andre Miller and Derek Fisher, two old guys. How is Kidd going to keep up with Westbrook? If Westbrook plays smart then he should have a field day against them.
Durant and Dirk cancel each other out I think, and Westbrook is the third best player in this series. Thunder in 6.
