The New York Knicks never could contain Jaylen Brown and on the last play of regulation completely lost track of Marcus Smart.

More mistakes than they’d like, but not enough to ruin their season opener.

“At the end of the day, we found a way to win a game,” Julius Randle said.

Randle scored 35 points, Evan Fournier made the go-ahead 3-pointer in the second overtime and added 32 against his former team, and the Knicks outlasted Brown and the Boston Celtics 138-134 on Wednesday night.

Brown scored a career-high 46 points after overcoming COVID-19, playing 46 minutes after spending most of the last 10 days in quarantine.

“My breathing felt irregular but fine for the most part,” Brown said. “Toward the end, I could feel my heart beating through my chest.

“It would have been better if we got a win,” he added.
