Entering Tuesday's rematch of the Western Conference semifinals with the Portland Trail Blazers, the Golden State Warriors ranked fourth from the bottom of the NBA in defensive rating, allowing 108 points per 100 possessions. If we learned anything from those first three games, in which the San Antonio Spurs blew out the Warriors and the winless New Orleans Pelicans and Phoenix Suns gave them scares, it was that replacing Andrew Bogut, Festus Ezeli and Marreese Speights with Zaza Pachulia, David West and JaVale McGee over the summer was no immediate upgrade defensively.
