I think we focus too much on the fantasy basketball nature of these moves, rather than fit. It is the same problem done of those bad US Olympic teams had. More talent doesn’t necessarily equal better. LA is a current example- when they got Westbrook a lot of people were freaking out about how good it made them.
Russell makes LA marginally better, in my opinion. But how does a Russell/Lebron/Davis core differ from the current? It is still a terrible fit. One might argue that the switch from Russ to Russell is worse for AD. And they still won’t stop anyone.
The same is true of Dallas. Kyrie innDallas looks amazing on paper. But who plays the wing, or any defense, or even tries on defense.
Conley in Minnesota would be the best fit of all, imho.
