The statistics currently being tracked is more offense focused. Bad Boys of Detroit, the Bulls, and the Spurs had solid defense that helped them win but not necessarily show up in statistics unless you do a game-to-game analysis of the opponent's average offense performance vs performance against a specific team.
Other than that, it's a pretty interesting thought/analysis... Just incomplete... but I'm sure someone can do a much more complete PhD thesis on this and get funded by some NBA team
