Golden State Warriors head coach Steve Kerr concedes his side have hit "rock bottom" after conceding a massive 91 first-half points in their 143-113 loss to the Brooklyn Nets on Wednesday.

The Nets' first-half haul was the third largest in NBA history, while the result condemned Golden State to back-to-back 30-point losses for the first time since 2001, having lost to the New York Knicks 132-94 on Tuesday.

The reigning champions were without Stephen Curry, Klay Thompson and Andrew Wiggins for the defeat, which leaves the Warriors at 15-18, with an abysmal 3-16 road record, ending their six-game road trip with just one win.

"Our spirit is fine," Kerr told reporters. "Our energy is good. The guys are committed.

"We're just right now at that point that pretty much everybody goes during in an 82-game season, most teams anyway, [where] you hit rock bottom with injuries, schedule, fatigued, whatever it is.

"You take it on the chin, the whole key is how you respond to that. I have no doubt our guys will respond but we've got to clean up the execution. Turnovers are a killer."

The Warriors trailed by as much as 44 points at the Barclays Center, with the Nets leading 91-51 at half-time.

Golden State gave up 21 turnovers for the game, with shooting guard Jordan Poole responsible for seven of those, finishing the game with 13 points on four-of-17 shooting.

"You can't play defense recovering from a turnover so that was the biggest issue to start the game," Kerr said.

"We were just trying too hard to make plays and getting out of control and then they made everything. They were phenomenal in the first half. I think they were 13 from 19 from three."

On Poole, Kerr added: "He forced it tonight. He got in a rush. We're going to live with Jordan's mistakes. He's a young player, he's still learning a ton. He's a great talent.

"Really proud of his development, but the development continues. Part of that development is having the best guy on him with Steph Curry out."

James Wiseman, who was second overall pick in the 2020 NBA Draft, offered a bright point for the Warriors with 30 points from 28 minutes off the bench, having had an indifferent season to date.

"James did a great job tonight," Kerr said. "It was fun to see him let loose and get some minutes and make the most of it. He did a lot of good things offensively… But when you lose by 30, it's small consolation."

Kevin Durant top scored for the Nets with 23 points with seven rebounds, five assists and four steals, while Kyrie Irving was absent with calf tightness. Ben Simmons contributed 10 points with four rebounds and eight assists.
