There's a lot to unpack here, so let's get to it.Stephen Curry is undoubtedly a top-three player. If he's behind Kevin Durant — and obviously I think he is now anyway, although last season I didn't hold that opinion — it's by the slimmest of margins. Curry is spectacular. He was hurt for most of the playoffs, and defenses keyed in on his tendencies independent of any injury. That his style is perhaps vulnerable in a seven-game series takes nothing away from his regular-season success. He was the unanimous MVP in 2015-16; anyone who tells you otherwise is selling something.However, the playoffs did serve as a nice reminder both of how the game changes in the postseason and how good Durant is. Where KD separates himself from Curry in my book is on defense. As mind-boggling as it is to say, Durant isn't the offensive player that Curry is. Curry put up the greatest offensive season ever last year, an 82-game roasting of the competition that Durant has never touched.What Durant did against the Warriors in the Western Conference finals, though, was absolutely remarkable. He locked down Draymond Green for most of the series, grinding Golden State's otherwise impeccable offense to a screeching halt. For those seven games, KD showed that his 7-foot stature and arms that reach from the past to the future don't just make him a scoring marvel; he's also one of the top three defenders in the game when he needs to be.Is it unfair to put so much stock in one postseason? Perhaps. As good as Curry is, and despite the fact that he has one ring to KD's zero, I'm still taking Durant as the best player on the Warriors.
