I'm a little more bullish on the T-Wolves and Magic because they are more physical teams than OKC.
Muscle may be less important than it used to be... but it still matters, especially in the playoffs (IMO).
I tend to be a bit suspicious of teams that have underperformed and then suddenly seem to "click". Not that it doesn't happen, it just seems like most often you see teams building, learning and improving each year ala the Warriors and currently OKC or who use big trades/FA signings.
