Well, OKC would be doing better with a healthy Ibaka, but even at equal strength, SA is a better team. At the moment. The core of OKC is very young, and SA is a fairly old team. In a few years after Duncan and Ginobili retire, and Parker is a few years older, OKC will do their share of steamrollering.
Hard to believe the Mavs pushed them to 7 games.
