Durant is known for leaving the team if he knew that he can’t carry it or get a great achievement on it
That's not true, he leads the Warriors in 2 straight championships and still he leaves the team.
Yeah, he helped the Warriors for two seasons to take the ring, and then the team has proven too that they can make it even without KD.
Durant will try to prove something and that is if he can carry the team, and the experiment with the Nets was a failed one and now he is looking for a new team to experiment with.
He's like that typical guy that really wants to prove something that he can do. He's done that part for him with the help of his former teammates on GSW. Now that he seems to be f*cked up with the Nets, he has to do something to find a better team that has a chance in qualifying in the finals.
