Yeah, I think we've discussed this before, and we can just politely disagree.
Durant was the first time a tip-top player went to a team that was already the prohibitive favorites to win it all. Big, big difference. GS wins with or without Durant. That makes Durant a freeloader. Miami with just Bosch and Wade doesn't win, and it wasn't an established, prohibitive favorite when LBJ went. Big difference.
We have discussed this before. Your point was as irrelevant then as it is now. KG agreeing to join up with 2 HoF'ers, LeBron going to Miami, LeBron going back to Cleveland; all not nearly as different as you like to think.
