It’s not this simple, except on some level it is:
Kevin Durant watched the Warriors play and thought their system looked like fun. Like something he wanted to be a part of.
In response to a question, Durant said Monday he watched Game 7 of the NBA Finals — a loss by the Warriors to the Cavaliers, giving Cleveland the title — and told his agent playing for Golden State he’d like to play for them. Via Anthony Slater of The San Jose Mercury News.
With Durant and Russell Westbrook, the Oklahoma City Thunder made the fewest passes of any team in the NBA last season — and they had the second best offense in the NBA. With fantastic shot-creating talents like Westbrook and Durant they played to their strengths. The lack of passing was in part due to them initiating their offense late in the clock more than most teams, but with talents like Westbrook and Durant it didn’t matter. It worked.
It was just not the style Durant wanted.
