Why is this Top 75 list being treated as a definitive source of who is a top quality player in a team? Most of these top xx lists are generally subjective. On the topic even before Durant joined, Curry had Klay, Green and Igoudala all of whom made for a top level playoffs team, plus some decent pieces in support. Even in 2016 when they had one of the starters go completely invisible, they only went out due to Green's stupidity, else that would have been a 4-1 close at the oracle. Durant joining obviously took it to ridiculous levels but it was by no means a team short on talent especially Klay who was one of the most explosive weapons in the game.
For me like I said before Curry's biggest credit is in transforming how the sport is played and being the poster boy for the current style of play, as well as being the centerpiece of one of the best offenses ever created which he has maintained while teammates have come and gone. I wouldn't necessarily have him as someone who could get you rings without a top level supporting cast especially looking at the 15-19 years when they got to 5 finals in a row. Doing it this year would definitely add that sort of a legacy to him as this team for sure isn't as star studded as those but still overall, I don't see it as a strong argument for him in particular.
