I don't agree that KD had no other options in 2016 that would have led to championships. He interviewed with GSW, Spurs, Clippers, Boston, and Miami. From a basketball standpoint GS and the Spurs were the clear top options. Boston was a distant 4th behind the Clippers, plus I just cannot imagine Danny Ainge coming off well to a guy like KD. The Heat roster was pretty trash. From a basketball standpoint they would have been the worst choice.
The Spurs would have likely been dominant with KD, Kawhi, and Aldridge. A functional Danny Green as a 3 and D guy with occasional bursts of old school Manu to steady the second unit? Gimme some of that please. I think the non-basketball factors made San Antonio a non-starter. He'd already done his time in small market conservative culture purgatory at OKC. I can definitely understand wanting to go somewhere that being a young famous multimillionaire would be more fun. Paintball doesn't strike me as KD's scene.
The Clippers would have been fucking scary on offense with CP3, Blake before the precipitous decline, Redick, a still-serviceable DeAndre Jordan, and Jamal Crawford off the bench. But I think there has to be some of that same Ainge-effect there with the personalities of CP3 and Doc Rivers not really being KD's style. Not sure they would have been able to match up with the Warriors on defense, but they could probably outscore anyone.
So, yeah, he had options, but the Warriors were clearly the best option, not just in terms of forming a dominant super team that would guarantee titles, but in terms of basketball culture, personality fit, and non-basketball opportunities. That's a lot of words to say it's weird that people think making the obviously best decision detracts from his greatness and even weirder that the continued success of a franchise that is in the top 3 or 4 managed teams in the league* detracts from his greatness. Haters gotta hate I guess.
* Warriors, Spurs, Heat, Celtics probably in that order, IMO.
