"Him being a leader, him being the best player on the team, him and Russ - at the end of the day you can sit back and make excuses about 13 to 14 guys, but without those guys you wouldn't even have been up 3-1.
"I watched that series, I was at home watching that series. They should've won the series, they should have went to the NBA Finals, they should have played Cleveland that year. They didn't, they gave up a lead.

Durant apparently said, through the unverified accounts, that OKC had very little aside from himself and Russell Westbrook, and he therefore couldn't win a championship with that roster. The reigning Finals MVP also insinuated that he didn't like playing for the Thunder and had issues with head coach Billy Donovan.
Those factors played a part in his decision to leave for the Golden State Warriors - who mounted a 3-1 series comeback in the Western Conference Finals in 2016 - in free agency last summer.
