People often define themselves by what they are not as opposed to what they are. You see it all the time. "Would this Warriors team beat the 90's Bulls?" is a prime example of this way of thinking.
There is no way to ever know, and the premise is flawed. The Warriors are at peace with their identity, which terrifies the rest of the league. The Warriors have realized that if they become the best version of themselves, if they strive for personal perfection as opposed to comparable perfection—looking over their shoulder at other teams and at other players—if they find this personal level of perfection, or at least actively strive towards that ideal at all moments, then everything else falls into place.
