2-5 in the East right now is an absolute mess. Only 2 in the loss column separates 2 from 5.
At one point the standings were:
Miami Heat 24-16
New York Knicks 23-17
Then the Knicks proceeded to win 7 in a row, while the Heat have lost 7 in a row. That's pretty weird. Now the Knicks are a serious threat (along with the Cavaliers) to the Bucks and 76ers for the 2 and 3 seed, while the Heat will be battling with the Magic and Bulls for homecourt advantage in the play-ins.
In the mean time the West is an absolute rollercoaster. You have the Timberwolves, Nuggets, Thunder and Clippers going for the top seed. Suns (who are climbing up), Kings, Mavericks and Pelicans are fighting to secure a playoff-spot. And Lakers, Jazz, Rockets and the Warriors are trying to at least make the play-in.
I think the play-in change has been an absolute success. How many teams would be coasting soon or starting to tank with the old-top-8-rule because they wouldn't have much to play for?
