Draymond Green has questioned the Golden State Warriors' "will to defend" after they slipped to 29-29 for the season in their last game before the All-Star break.

The reigning NBA champions were beaten 134-124 by the Los Angeles Clippers on Tuesday, conceding 44 points in the third quarter at Crypto.com Arena.

The Warriors have conceded on average 118.5 points per game this season, with only the Charlotte Hornets (119.1), Detroit Pistons (119.7) and San Antonio Spurs (122.7) faring worse.

That is a significant rise on their average of 105.5 points against per game in the regular season last year, which was the third-best in the league.

"It has to come from within," Green said. "Defense is all about will, a want to defend.

"Defense isn't fun. You've just got to do it if you want to win, and we haven't.

"It's the will to defend, stop and guard your man, and sink, and drop the box and rotate. Defense is just one or two steps extra... that's all will, and we don't have that as a team."

Kawhi Leonard top-scored for the Clippers with 33 points, while Norman Powell recorded 24, getting away 17 field-goal attempts despite only being on court for just over 25 minutes.

"Every guy has to decide to take on that challenge himself," Green added. "That challenge isn't just guarding the ball. The challenge is I'm supposed to be there to help, and that guy has to be able to trust that I'm going to get there. 

"If he doesn't trust that I'm going to get there, then what do you do? You foul. We all know that's been a problem for us.

"I can be better. I'm as much of a culprit as anyone else. I'm not going to point the finger at anyone or point blame. If you're a leader at something and you are failing at it, it's your fault."

Green also acknowledged Golden State's need to improve quickly or risk missing out on the playoffs, as they sit ninth in the Western Conference.

"It's now or never," Green said. "We are .500 at the break. Middle-of-the-pack team with those middle-of-the-pack stats.

"You've got to come out of the break and win and do it at a high level, or you go home at the beginning of April. I wouldn't be happy with that. But that will be the result if we don't get there."
