The Nets’ brightest young player is down and out for at least a few months. Now they need their biggest disappointment to wake up from his season-long slumber.

Caris LeVert’s dislocated right foot has created an opening for Allen Crabbe, and coach Kenny Atkinson seems willing to give the veteran wing a shot at filling the canyon-sized void left by losing the Nets’ leading scorer.

“I take Allen Crabbe’s body of work — his whole body of work — and think he’ll get out of this little rut, and it’ll [get to] where it belongs,” the Nets coach said Thursday following practice, a day after he inserted Crabbe into the starting lineup.

The 6-foot-6 Crabbe’s numbers are down across the board, the lowest of his career since he became a regular with the Trail Blazers in 2015. His minutes (23.4) have fallen, his shooting percentage (25.7) is ugly and his turnovers (1.3) are up. He’s scoring 6.5 points per game and has failed to reach double figures in his past nine games, paltry production for a player in the third year of a four-year, $75 million contract.

“It’s just really something I’m going through right now and I’ve got to figure it out,” he said as the Nets (6-9) prepared to face the Wizards on Friday in Washington. “Especially with the injury to Caris, guys have to step up, including myself. I just gotta stay positive about it and understand that it will pass and I’ll get back to my normal self eventually.”

It didn’t help that Crabbe missed some time with a sprained left ankle in the preseason, and LeVert got off to a such a fast start, it reduced him to a reserve role. But that has changed now. The Nets need him to find a way out of this funk.

“It’s almost like a guy that’s hit .340 his whole career and all of a sudden he’s mired in a .220 slump,” Atkinson said, using a baseball analogy. “I think it happens to every good player. I don’t know about the greats, but every really good player, they go through it.

“Listen, we’re searching, and I think he’s searching. He keeps working.”

Crabbe spent extra time after Thursday’s practice getting up shots, working on the kind of attempts he will take in games. His mindset is to shoot his way out of this.

“Right now that’s all I’m doing and I’m just waiting for that breakthrough,” he said.

Atkinson declined to say if he will keep Crabbe in the starting lineup. He is considering starting lead guards Spencer Dinwiddie and D’Angelo Russell together, though he is worried what elevating Dinwiddie would do to the second unit.

Crabbe playing well would solve a lot of problems. Atkinson did seem encouraged by his performance in Wednesday’s loss to the Heat, when he scored six points on 2-of-6 shooting from the field in 26 minutes.

“I can’t say I didn’t like what I saw,” Atkinson said.

The Nets have allowed at least 116 points in each of their past three games (all losses) and while rim-protecting dynamo Jarrett Allen missed the past two games, Atkinson said he doesn’t believe that should explain the poor performances on that end of the floor. … Allen (illness) and Rondae Hollis-Jefferson (ankle) are both questionable to face the Wizards. They will travel with the team. Allen practiced Thursday.

“We still I think can do better than we’re doing right now,” he said.

Dinwiddie echoed Atkinson.

“I think our defensive intensity a little bit has been down,” the backup guard said.
