When the Boston Celtics blew a 3-1 series lead to the Philadelphia 76ers in the first round of the playoffs, it felt like a nightmare scenario. Now, thanks to the New York Knicks, that collapse looks even more painful.

The Celtics had everything going for them—home-court advantage, a deeper roster, and a chance to face a familiar rival in the second round. But instead of closing the door, they lost three straight games to a seven seed, crashing out of the postseason in historic fashion. It was the kind of meltdown that leaves fans shaking their heads for years.

Enter the Knicks, who have since poured salt—make that sulfuric acid—on Boston's wounds. New York just swept the same 76ers team that ousted the Celtics, and they did it with surgical precision. Only one of those four games was close; the other three were double-digit blowouts. The Knicks averaged a staggering 124.3 points per game against Philly, while Boston couldn't even crack 100 points in any of their four losses to the Sixers.

What makes it worse? The Knicks exposed what the Celtics couldn't—Philadelphia's defense. New York attacked with confidence, moving the ball and finding easy looks. Boston, by contrast, looked lost and tentative, letting the series slip away when it mattered most.

In the end, the Knicks proved they're not just a better team than the Celtics right now—they're a more serious one. And if Boston had somehow advanced, it's hard to imagine they'd have fared any better. The Celtics entered the playoffs as Eastern Conference favorites. Now, that title belongs to New York. And for Boston fans, that sting isn't going away anytime soon.
