I really would like to know the answer to this. But I think, in NBA, there are very few pure offenses or pure defense teams that captured the Championship.

The key to winning championships is balance. A good offense should be coupled with a good defense. This is why the Clippers have the edge over lakers and rockets. Both Kawhi and Paul George are top-notch two-way players. They can perform on both ends of the court. Just look at how successful the Spurs have been in the last decade. They are a perfect example of a good balance between offense and defense.
