You know it's bad when your own fans turn on you at home in the playoffs. The Boston Bruins gave up four first-period goals at TD Garden against the Buffalo Sabres - the first time they've done that since the Hartford Whalers did it to them back in 1991. And the Boston faithful let them hear about it, booing them off the ice after the first period.

Four goals. In one period. In a playoff game. At home. That's not just a bad start - that's an organizational embarrassment. That's the kind of performance that gets coaches fired and rosters blown up.

The Sabres smelled blood early and went for the throat. Bowen Byram scored the fourth goal, and by that point, TD Garden sounded like a library. The fans who stayed were letting the team know exactly how they felt, and it wasn't pretty.

Here's the thing about Boston sports fans - they're passionate, they're knowledgeable, and they have zero patience for teams that don't show up. The Bruins looked like they were skating in quicksand. Defensive breakdowns everywhere. Goaltending that couldn't stop a beach ball. Effort that suggested they'd rather be anywhere else.

For Buffalo, this was validation. They've been the little brother in this rivalry for years, watching the Bruins make deep playoff runs while they rebuild. To come into TD Garden and do this? To dominate Boston so thoroughly that the home crowd boos their own team? That's a statement.

The Bruins now face elimination and serious questions about the direction of the franchise. Is this core done? Do they need a coaching change? How do you give up four goals in one period in a playoff game at home?

I've covered playoff hockey for two decades, and I can tell you - when your fans boo you off the ice in the playoffs, that's a wound that doesn't heal easy. The Bruins better find some answers fast, because the Sabres aren't going away, and that crowd at TD Garden is going to be even less forgiving next game.

That's playoff hockey, folks. Show up or go home. Boston didn't show up, and now they're one game away from going home for good.
