Kevin Durant: The former MVP didn't seem to be happy in Oakland all season. But would "KD" really leave the team, which in 2019/2020 would aim for a fourth title in a row? Yes. Kevin Durant is different!
Kawhi Leonard: Last year Leonard really wanted to go back to his hometown L.A. Then the trade to Toronto happened. It's quite possible that he doesn't even know where he wants to play in 2019/2020. It is also possible that he will end up with the Clippers next season.
Kyrie Irving: There are more rumors about the 27-year-old than any other star-free agent. The Knicks are in the discussion, where he could directly form a new Superteam with Durant. Even more "super" would be a reunion with LeBron James on the Lakers.
