Stephen Smith called Durant's decision to go to Golden State Warriors "the weakest move by a superstar ever" ... "I don't think there is any way to deny that.." "He ran away from the challenge that he faces ... to jump on a bandwagon."
I think that the value system that Smith uses to judge Durant is a nebulous creation of the media that has more to do with comic books than real life.
The superstar system only values the unique talent of individuals and the way they impress their will on the game.
I think that Durant wants to be part of a team that plays team basketball and not be the hero atlas trying to beat a whole team by himself.
The bandwagon that is Golden State is not just the talent of the players: it is how they play, how they enjoy playing basketball, being good teammates, and how the whole is greater than the sum of the parts. One could argue that Durant-Westbrook are more talented than Curry-Green-Thompson, but it is not just talent that wins: it is playing the right way as a team that wins.
Celtics are headed in the right direction with team building and having a winning culture. No shame in being 2nd or 3rd choice for Durant. Picking Curry, Thompson, Green over Smart, Bradley, and Crowder as teammates makes a lot of sense.
