MORE: The best players to leave their team during their best years

A source familiar with Durant’s thinking said, “Ultimately he got frustrated and felt that they had plateaued. (Donovan) came in, and he still had the same issues that he had with Russ under Scotty. The offense didn’t change much. He still had to take a ton of contested shots every game; and that’s when he had the ball at all.”

Durant does not anticipate having the same issues under Steve Kerr’s system in Golden State.

“He’s never going to have a game in Golden State where Steve Kerr has to say at halftime, ‘You guys need to get Kevin the ball,’ which happened in OKC,” the source said.

Even with his level of frustration, Durant would not have left the team had the Thunder won the NBA title, the source believes. OKC blew a 3-1 lead to the Warriors in the Western Conference finals.
