This essentially was like “Weekend at Bernie’s” for the Knicks, who appeared comically dead for the majority of their two latest losses to the NBA’s elite.

Yes, they slashed a gaping 27-point hole to four in the third quarter Sunday afternoon in Boston, only to allow the Celtics to score the next 10 points en route to a 118-105 victory at TD Garden.

Another opportunity for the Knicks to prove they belong in the same contending conversations with the defending league champs fell harmlessly to the parquet floor. The back-to-back decisive road defeats in Cleveland (Friday) and in Beantown dropped Tom Thibodeau’s team to 0-7 this season against the three teams that began the day with a better overall record, also including two losses to the West-leading Thunder.

Sunday’s second-half comeback bid notwithstanding, those seven defeats have come by an average margin of 20.1 points.
