It’s that kind of season for the Nets when even the good news comes with question marks.

Starved for size, Brooklyn got back their biggest big man with Tuesday’s return of Day’Ron Sharpe.

But now comes the tough call of just how to use the young center, and how he’ll impact a defense that’s finally found its footing.

“It’s gonna be a Rubik’s Cube,” coach Jacque Vaughn said of juggling big-man minutes among Sharpe, Nic Claxton and Ben Simmons. But he’s also going to have to juggle schemes as well.

The Nets shored up their leaky defense by going back to their switching scheme, right before Sharpe went down with a hyperextended knee.

Now that he came back against Boston, will they go with a scheme that’s working, but one he’s ill-suited to play?

“Whatever they need me to do, I’m gonna do. Whether it’s switching, if it’s dropping,” Sharpe told The Post. “Probably when I’m in the game, we’re probably going to drop a little bit more, but if I’ve got to switch, I can do it, too. So just whatever J.V. needs us to do, whatever is needed.”

For the Nets, the move away from their failed drop-coverage experiment was needed. Switching helped the roster, particularly Claxton, one of the best switching bigs in the league.

But Sharpe is conspicuously vulnerable in the scheme, with the Celtics uniquely suited to take advantage of that.

“Yeah, it changes because we don’t want Day’Ron playing isolation ball against Jayson Tatum,” Vaughn said. “So we’ll have to continue to [change], and that’s the part of without our group being totally together and practicing and figuring out the different lineups and what it’s going to take with different lineups, different solutions and how to cover for each other with a different lineup.

“So that’s going to take a little time. We’re going to try to speed that timeline up. But we were a lot of games without Ben [Simmons], without Dorian [Finney-Smith], without Day’Ron, and that’s a lot of rebounding for us. So to have all three of those guys back in the fold, it’s a benefit for us for sure.”

Claxton is arguably among the NBA’s best switching centers, but the Nets tried drop coverage early on as a way of getting Sharpe on the floor.

The young rebounder had risen to Vaughn’s offseason challenge to be more professional and focused, but the Nets were getting hammered on the boards.

The scheme took away Claxton’s aggressiveness, and the Nets’ struggled on that end of the floor.

Through much of the season, Brooklyn was among the worst defensive teams in the league.

That is, until they finally pulled the plug on their failed experiment with drop coverage on Jan. 5, going back to switching against Oklahoma City.

Since then they came into Tuesday fourth-best in opponent field goal percentage (46.9), 3-pointers (11.6), and fifth-best in opponent effective field goal percentage (53.6).

And after bemoaning their lack of turnovers produced all season, Brooklyn has even notched the eighth-most steals since then at 8.4.

All that came without Sharpe, who hurt his knee Jan. 7, the game after Brooklyn went back to switching and throttled OKC.

Now that he’s back, the Nets seem intent on sticking with the defense that works.

“The big part of us changing schemes was because we didn’t rebound the basketball. So we had plenty of evidence that it was just going to make it difficult,” Vaughn said. “If we have bigger bodies — especially now in that starting group, looks like Doe and Ben and Nic at the same time — we should be able to cover up for each other, be able to guard one-on-one and still rebound the basketball.

“So that’s the piece we’re looking forward to seeing. But there’s definitely something schematic-wise, also philosophical-wise of what you’re giving up, which we were at the beginning of the year, that we found a medium for us to live in and get better at.”

Sharpe finally returned after missing 15 straight games, itching to get back playing whatever scheme was needed.

“I’ve been fiend-ing, man,” Sharpe said. “Just happy to be back.”
