Golden State Warriors coach Steve Kerr described officiating standards as "disgusting" after Nikola Jokic made 18 free throws in the Denver Nuggets' Christmas-Day win over his team.

Jokic made all 18 of his free throw attempts as the Nuggets posted their fifth successive win, which represented a career-high tally as he finished with 26 points in his team's 120-114 success.

Ten of those came in the third quarter as Jokic drew foul after foul from the Golden State defense, prompting Kerr to lash out at what he sees as a league-wide problem.

"I have a problem with how we are legislating the defense out of the game," Kerr said after the Warriors slipped to 15-15.

"We are enabling players to B.S. their way to the foul line. If I were a fan, I wouldn't have wanted to watch the second half of that game. It was disgusting. 

"It was just baiting refs into calls, but the refs have to make those calls. The players are really smart in this league. 

"For the last decade, they've gotten smarter and smarter. We have enabled the players, and they are taking full advantage. It's a parade to the free throw line, and it's disgusting to watch."

Four-time NBA champion Stephen Curry, who was held to 18 points, echoed Kerr's sentiments as he said: "It does cater to the guys who can sell calls. 

"There is physicality, but it's tough because it is inconsistent, at times, on either side.

"On a night like tonight, when you feel there is physicality on one side and then ticky-tack on the other, it changes the complexity of the game. 

"I'm not saying we don't foul, but consistency is key when understanding how you can defend."

Jokic, though, denied actively trying to sell calls and said aggression became key to his performance after a slow start.

"I was missing shots, so I was just trying to be aggressive in another way, maybe play a little more physical" Jokic told ESPN.

"It just happened to be that kind of night. This is the most I've ever had."
