To me to judge the Kings situation the question becomes, How many games have the Kings won the last couple of years
without Cousins?
Since OKC is mentioned above and we know Durant missed a bunch of games and OKC still won 45 games but missed the Playoffs
So if I treat this sort of like math and don't even use the eye test I can say with the above facts Cousins makes his team win. And if that is true..................Darn it, I guess I am not an analytics guy and certainly not 5 moves ahead

We know Durant is really good. I mean MVP good yet OKC still won. What does this say about Durant?
Here is an interesting quote from nba.com:
"However, the 1993-94 Bulls proved there was life without Michael Jordan. Although Chicago didn't win its fourth straight championship, it posted a
55-27 record (for second place behind the Atlanta Hawks in the Central Division) and advanced to the Eastern Conference Semifinals."

So those Bulls were still really good without Michael. But "Chicago didn't win its fourth straight championship"

Those Bulls won 55 games without Michael. We know Michael is the greatest.
Using these examples the eye test makes me think that there is something to this "talented players that make their teams win" question. But there may be something to the rumor that basketball is a team game.
Anyway back to the question "What is the distinction that you make between talented players and talented players that make their teams win?"
For the past two seasons Demarcus Cousins makes the Kings win. If he does not play the Kings lose! Can anyone dispute this?
