Defensively, the Spurs weren’t all bad. In fact, their interior defense was fantastic. At the rim, the Thunder connected on only 57.3% of their shots. Considering that they typically shoot 65.6% from that distance, Duncan and the rest of the team did a wonderful job of shutting down the paint.
Extending the area of focus out further, San Antonio’s defense was very good within fifteen feet of the basket. From fifteen feet and in, the Thunder shot only 48.5%. During the regular season, they shot 56.6% from that range. That's a colossal drop of 16.7%. Thus, even though the Thunder have breathtaking athletes, it's difficult to see the athleticism advantage in the stats alone.
