Are the Brooklyn Nets the most STACKED team in NBA HISTORY ?

I would like to offer the 85-86 Celtics as a contender for the title. 

No, they have to get passed the warriors first

No. They aren't even very good. 

Harden is at average player at best. Yes, he's decent on offense (not good) but he cancels all of that out by being horrible on defense

Durant is a decent scorer but his lack of rebounding and defense keep him from being an elite player, Remember, GS was actually better without him. 

If they're so good, why do they only have the 3rd best record with several teams so close? 

If you want to look at stacked teams you need to start before 1990.  Check out the Celtics and Lakers from the 80s or the Celtics from the 60s. 

They're one of them, but the current Lakers and the Warriors of the past are too.

Explain "stacked" please.

Maybe the 2nd stacked team the most stacked team for me is 2018 GSW.

They remind me of the Karl Malone Gary Paton Lakers. They might have the names, but how many of those names are in their primes?

KD/Steph Warriors

No.  They are the most STROKED team in the NBA because of all the handjobs they give each other.

anything is possible
