Assuming that Durant goes back to OKC
I see the West like this-
Tier 1 Contenders
1 Warriors
2 OKC
3 Spurs
Tier 2 - Pseudo contenders
4 Clippers
Tier 3 Likely playoff teams
5 Portland
6 Grizzles
7 Utah
Tier 4- not terrible but ...
Minnesota
Houston
New Orleans
Dallas
Denver
Tier 5 - Just bad teams
Sacramento
Phoenix
Lakers
I think people are underestimating how good Conley, Gasol and Parsons are when healthy. Though I worry about their coaching change.
I am assuming that Portland fills out the rest of their roster intelligently.
The Clippers still have 4 very good players. They probably need to trade someone to create some depth.
