As one of the hottest teams in the NBA over the past month, it's no surprise that the Oklahoma City Thunder have finally found their way to the top of our rankings. The Thunder have the number one defense in basketball, despite arguably their best wing defender, Andre Roberson, not having played any games so far this season (with at least six more weeks until he finally returns.) A somewhat surprising addition to the top of the list is the New Orleans Pelicans, with a less than inspiring 4-6 record over the past 10 games, despite having a top 3 player in Anthony Davis. Meanwhile, the Chicago Bulls are once again in the NBA's cellar, thanks to their current seven games losing streak.
