You don't want to double Jokic. You want him to shoot 25 shots per game and play defense, because that takes more out of him than taking 18 shots and standing still and dishing out 7 assists.
There was a sequence near the end of the game. Nurk got the ball down low and had four Nuggets around him. Jokic was the fourth, coming in from behind. He was walking in. Nurk lost the ball, got it back, scored and was fouled while Jokic stood and watched from 2 feet away.
You make Jokic get up and down the floor, have to exert energy making offensive moves and make him have to exert energy on defense. He's not in the kind of physical condition to be THAT player. He needs possessions that he can take off and just survey the court and make backdoor passes.
You make him shoot. A lot.
