they upgraded defensively by adding Kidd, Brower. Melo has actually been a good defender more times than not so far this year. He still has his lapses where guys pretty much just walk by him and he's still a horrible rebounder. But the big difference has been Woodson, his defensive schemes call for a lot or movement, a lot of switching, basically a lot of team defense with the fall back being Chandler and people have bought into it. Also keep in mind that they are a halfcourt team so the score will naturally hover right around 100 when you play them and if they play good defense, you are going to get 85-90 points on them at most.
