The concerns bubbling around the Knicks had cooled in recent days, but Tuesday brought them right back to the surface. 

And that’s despite extending their winning streak to three with a comfortable final margin of victory. 

Because if it were almost any other team other than one of the NBA’s bottom-feeders in the Kings, they would have been buried. Against any quality team, this wouldn’t have been good enough. 

The Knicks committed 21 turnovers, allowing the Kings to score 20 points off them.

OG Anunoby had a whopping seven — including three straight turnovers to end the third quarter. 

They are lucky the Kings shot a woeful 16.7 percent (5-for-30) from 3-point range. Plenty of those were open looks, though — not exactly the result of strong perimeter defense. 

It meant the Knicks were not punished for a brutal first three quarters. They proceeded to outscore the Kings by 16 in the fourth quarter. 

So the lethargic Knicks were bailed out with a 103-87 win at Madison Square Garden.

After losing nine of 11 games, they have responded with three straight wins.

Their historic rout of the Nets followed by a chaotic win over the 76ers in Philadelphia provided some confidence they put their rut behind them and were returning to the standard they had held earlier in the season.

But Tuesday’s showing certainly wasn’t convincing — quite the opposite. 

“It was an ugly game,” Jalen Brunson said. “It wasn’t pretty. But we were able to grind it out and find a way to win. I think that’s very important for us.” 

The MSG broadcast repeatedly showed a puzzled Brown looking on from the bench, unhappy with what he was seeing. 

It was embarrassing when the Knicks lost to the Kings in Sacramento earlier this month.

The Kings, who are now 24 games under .500, proceeded to go 1-5 before Tuesday’s rematch. And for the majority of Tuesday, the Knicks were flirting with similar embarrassment. 

“I thought [the turnovers] were self-inflicted,” Brown said. “That’s not taking anything away from Sacramento. I thought we didn’t do a great job of playing off of two feet. Whenever you play off of one foot, you’re gonna get yourself in trouble. If you leave your feet with no place to go, you think somebody is open, there’s a good chance that the defense is gonna rotate and take that away and now you’re in trouble.

“We just have to do a better job of playing off of two feet.” 

It wasn’t until just over three minutes left in the game until that the Knicks finally took control, when Brunson scored seven straight points to put the them up by 12. Brunson finished with a team-high 28 points. 

Brown closed with Brunson, Miles McBride, Mikal Bridges, Anunoby and Mitchell Robinson on the floor, with Karl-Anthony Towns and Josh Hart notably on the bench. Towns hit two important 3-pointers early in the fourth quarter, but he and Hart both sat the final 6:51 of the game. 

Robinson and McBride were effective off the bench.

They finished plus-25 and plus-20, the two best marks on the team. Robinson recorded seven points, six offensive rebounds and two steals. 

“It was huge,” Brown said of Robinson. “He brought a level of energy, especially defensively, to the table that helped us get over the hump.”  

DeMar DeRozan, 36, turned back the clock and recorded 34 points. But he got little help from Russell Westbrook or Domantas Sabonis. 

Mikal Bridges scored seven points in the fourth quarter and finished with 18.

The win moved the Knicks into a tie with the Raptors — whom they face Wednesday in Toronto — for third in the East.

“It feels great,” Robinson said. “We’re really making a turn and we’re really getting our s–t together.” 

Maybe. But it would behoove them not to repeat Tuesday’s performance.
