Luka Doncic does not have answers for the dismal Dallas Mavericks defense, after another of his triple-doubles meant little in a loss to the Indiana Pacers.

Doncic posted 39 points, 10 rebounds and 11 assists on Tuesday, registering his 14th triple-double of the season.

The Slovenian is averaging 34.6 points per game this season, and is on course for a career-best PPG return.

Yet in spite of Doncic averaging 37.3 points in the past six games, the Mavericks have lost five of those.

"It doesn't matter," Doncic said when asked about his fine form. "I just want to win, man. That's it."

"I don't know, honestly. We know we got to fix it."

Coach Jason Kidd was equally as frustrated.

"We got the personnel. We got the team," said Kidd.

"This is actually a great test for us to be able to go through a hard time in March because it only gets harder in April and May and June.

"And so this is a great test to be tested in the sense that we're going to let go of the rope or we're going to continue to come to work. Everyone's coming to work. Everyone has the positive mindset, energy.

"Everyone's trying to do the right thing right now."

Kidd put the onus on Doncic's teammates to help out the NBA's leading scorer this season.

"Are we asking too much? I don't know if we're asking," he added.

"This is what he does. He's one of the best offensive players on the planet, and so this is what he does and so we have to help him on that end and we have to also help him on the defensive end. This isn't a surprise, he's been doing this pretty much his whole career.

"He's a walking triple-double. He's doing everything to help the team win. We all have to pitch in and help him."
