There was a huge difference between the teams in the west and east with the west having better records since the mid 2000's. In '09 all 8 teams in the playoffs from the west had 50 or more wins.However, things are very different now. Most of the teams suck because of the big dawgs stacking themselves with all the talent. The main reason for seeing these "streaks" this season is because the middle class is basically gone.
On another note, there was a hint from DH very recently that he is extremely unhappy with the situation in Orlando and that he would prefer to be somewhere else. Specifically, he had said, "lakers or knicks".
