You have two legit teams, OKC and Cleveland.
Besides that though, this has been a pretty crazy NBA season. Feels like upsets are happening constantly, but also there's a lot more drama in terms of injuries, young teams rising in the standings, contending teams slumping, etc.
I don't really think you can rank 3-10 in the entire NBA without having to really think about things, which shows there's some parity (but also just bad, inconsistent basketball). In a way though it makes it exciting. Like, are Memphis and Houston for real? Are the Knicks truly contenders or pretenders? Same with the Wolves and Nuggets. Hard to tell. Kind of feels like "any given night" for most teams unless you're OKC-CLE just steamrolling everyone.
