SAN ANTONIO — How bad was the Knicks offense in the first half?

For the opening 22 minutes of Wednesday night’s ugliness, no starter besides Karl-Anthony Towns hit a field goal.

Not one.

Mikal Bridges, Josh Hart, Miles McBride and OG Anunoby missed their opening 20 attempts, including an airballed midrange jumper from Bridges, as the Spurs took a 28-point lead in the second quarter.

It was enough of a cushion for the Spurs in their 120-105 victory Wednesday night at the Frost Bank Arena.

The Spurs are depleted and facing a lost season.

Victor Wembanyama (blood clot), De’Aaron Fox (finger surgery) and Gregg Popovich (stroke) are all done for the season.

The Spurs were relying heavily on youngsters like Sandro Mamukelashvili and Blake Wesley.

They had dropped 10 of 14 games before playing New York.

It didn’t matter.

The Knicks, playing their sixth straight without injured Jalen Brunson, couldn’t hit the Hudson River with a penny from the railing of the Staten Island Ferry.

They shot just 31 percent in the first half, including 4-for-19 on treys.

And even without the towering Wembanyama on the court, the Knicks were still outrebounded 52-44 for the game.

To their credit, the Knicks didn’t just roll over after the terrible start.

They started the second half on a 22-6 run, cutting their once seemingly insurmountable deficit to single digits in a matter of minutes.

They were threatening the biggest comeback in not only the NBA this season, but also in Knicks franchise history dating back to at least 1991-92.

But it wasn’t enough because Mamukelashvili, a Seton Hall product, produced the game of his life with 34 points, dominating the fourth quarter while hearing “MVP” chants. Stephon Castle, a front-runner for Rookie of Year, added 22 points for the Spurs (29-39).

Towns, the only Knicks offensive weapon, finished with 32 points, including 19 in the first half. Hart followed his triple-double from two nights prior with a dud — just two points in 35 minutes on 1-of-4 shooting.

Bridges shot 5-for-13 with three turnovers.

Other than missing Brunson, the Knicks (43-25) were at full strength.

Mitchell Robinson had been listed as questionable with “injury management,” but was declared available and scored 13 points with 11 boards off the bench.

Thibodeau wouldn’t rule out Robinson for Thursday against the Hornets, but the center previously sat one game of a back-to-back set earlier this month against the Lakers.

“We’ll deal with tomorrow, tomorrow,” Thibodeau said. “We’re just dealing with today, today.”

Still, logic suggests Robinson won’t be thrust into a back-to-back.

The plan with the 26-year-old, who hadn’t played in 10 months before returning from ankle surgery on the last day of February, was always to ramp up his conditioning and plot a course for playoff health while operating on a minutes restriction.

The Knicks have four more back-to-back sets this season, including next week against the Mavericks (Tuesday) and Clippers (Wednesday).

Thibodeau said Robinson is operating at a “guideline” of about 24 minutes and that will “probably increase some.”
