James Harden admits he is still trying to figure out how to play his best basketball for the Brooklyn Nets after an ordinary display in the 113-107 loss to the Phoenix Suns on Saturday.

Harden registered his fourth triple-double of the season, but he had seven turnovers and shot poorly, going none-for-six from three-point range for his 12 points under close guarding from Mikal Bridges.

The 2018 MVP also shot four-for-16 from the field, finishing with 13 rebounds and 14 assists, as his up-and-down season continues.

Harden is averaging 20.7 points, 7.6 rebounds and 9.2 assists per game this season, with his offensive output the most alarming decline on his 25.0 career average.

The 32-year-old averaged 24.6 points for the Nets following his January move from the Houston Rockets, with injuries impacting his continuity after the switch and into this season as well as developing cohesion with his new side.

"Honestly I’m trying to figure all that out right now," Harden said at the post-game news conference. “I’m trying to figure it out.

"Trying to figure out when to score, when to be a playmaker when to run offense, when to do a little bit of everything.

"Just trying to figure it out it’s been a little difficult especially since you know, well whatever, but it’s been a little difficult but I’m just trying to figure it out."

Nets head coach Steve Nash admitted it was a "tough night" for Harden, who was jeered by some fans at the Barclays Center upon his seventh turnover.

"It was a tough night for him," Nash said during the news conference. "Some turnover issues. He didn’t get a lot of good looks.

"That's part of our growth too, trying to figure out ways for him to be effective, even if he's not getting to the rim."
