Wednesday was a season opener to forget for Jalen Brunson and the New York Knicks.

The guard was an ugly 6-of-21 from the field during the 108-104 loss to the Boston Celtics. He also didn’t want to use opening-night nerves as an excuse when asked if some of the poor play could be attributed to that.

“It might be, but I hold myself to a higher standard,” he told reporters. “I just have to be better no matter what night it is.”

The addition of Brunson was a major reason the Knicks won a playoff series last season for just the second time since the 1999-2000 campaign. It was reasonable to expect the team to make a jump in 2023-24 with more continuity, but Wednesday was not an ideal start.

It seemed like the home team was on the way to a win when Brunson extended the lead to six with a floater in the final four minutes. However, the Celtics closed the game on a 13-3 spurt that included clutch shots from former Knicks big man Kristaps Porziņģis.

Brunson also missed a technical free throw during Boston’s final run, which was a glaring part of his overall struggles.

It wasn’t all bad news for the Knicks, as Immanuel Quickley added 24 points off the bench behind five made three-pointers. RJ Barrett also scored 24 points, but the shooting woes of the two go-to options were too much to overcome.

In addition to Brunson, Julius Randle was an even worse 5-of-22 from the field.

That simply isn’t good enough against an elite team like the Celtics, which is notable in a season in which New York will be compared to the likes of Boston and the Milwaukee Bucks in the Eastern Conference race.

Fortunately for the Knicks, Brunson has a track record of success and will surely turn things around as he holds himself to that standard. His next chance at a better showing will come Friday when they hit the road to face the Atlanta Hawks.
