The intent might be the same but there is 1) an order of magnitude difference in talent involved, 2) better harmony of pieces and 3) Durant playing a major role in OKC's choke job against the Warriors in the WCF. A better comparison would've been if LeBron left to join the Celtics or Spurs.
I fail to see how this Warriors team wins less than 65 next season, and maybe loses 1 game in the playoffs. It would be mildly disappointing otherwise.
