The Knicks once again faced a 20-point third-quarter deficit.

Once again they faced unlikely chances of pulling off a victory.

Yet once again, they did exactly that.

Tom Thibodeau’s team climbed back and beat the Boston Celtics 91-90 in Game 2 of the Eastern Conference Semifinals Wednesday night at TD Garden in Boston to take a commanding lead of the series.

Game 3 will be Saturday at Madison Square Garden.

Something special just could be brewing with these Knicks.

How the Knicks pulled off another comeback

Mikal Bridges scored all 14 of his points (he also had seven rebounds, five assists and three steals for the game) in the fourth quarter to cut it to single digits – all before making a huge defensive play on the final possession of the game.

Jalen Brunson, who had 17 points, drained a three to make it a seven-point game with just less than four minutes to go.

Josh Hart, who finished with 23 points, then cut it to five with a floater to cut it to five with three minutes left.

Karl-Anthony Towns later made it a one-point game after he got a tip-in off a Hart miss, drawing a foul and hitting the free throw to convert the three-point play with 2:30 remaining as part of a 21-point, 17-rebound performance.

Brunson then hit a step-back jumper with two minutes left to push the Knicks ahead by one, stunning the TD Garden crowd.

The Celtics were struggling to get anything, and Brunson hit a layup on the other end to make it a three-point game with a minute left as part of a 22-2 game-changing run.

But after he made two free throws, Jayson Tatum out of a timeout went the length of the court for a ferocious dunk that pushed the Celtics back up by one with 18.5 seconds left.

Brunson on the other end got fouled by Jrue Holiday as he attempted a jumper – he hit both foul shots to put the Knicks up 91-90 with 12.7 to go.

Tatum on the other end tried going to the basket but Bridges knocked it away.

That was the game as the Knicks and Bridges, once again, came up with a huge defensive play to help seal the win.

Another lackluster shooting night from the Celtics

It’s starting to become a trend – in this series at least.

Boston, a prolific three-point shooting team, struggled again from deep, going just 10-of-40 (25.0 percent) from beyond the arc.

Derrick White (3-of-11) had a tough night from deep, and so did Sixth Man of the Year Payton Pritchard (3-of-9). Center Al Horford was 0-of-5.

The Celtics in Game 1 went 15-of-60 from long distance, setting an NBA-playoff record in missed threes.

Again, Boston lives and dies by the three. If the Celtics keep shooting like this, the Knicks are in good shape.

Tenacious, tough Knicks

There’s been a lot of talk about how the Knicks lack the type of intensity and tenaciousness they had last season after trading away Julius Randle and Donte DiVincenzo and seeing Isaiah Hartenstein sign with the Oklahoma City Thunder.

But the Knicks in this series – and in the first round – have proven that’s not the case at all.

Teams don’t make 20-point comebacks in consecutive games by accident.

Regardless of how poorly the Celtics shot from three-point range in both games, the Knicks made all the plays they needed to make on both ends of the court when the game was on the line.

They didn’t fold in either game. They made huge defensive stops.

That toughness was on display. And that’s the type of intangible that goes a long way in the playoffs.
