There’s no telling what it’s going to take for the Bruins to put forth a 60-minute effort to at least put themselves in a position to win a game, let alone actually earn two points.

Playing in front of a packed house against their archrival on Hockey Night in Canada after waking up as the last-place team in the Eastern Conference didn’t do the trick.

The Bruins dug a 3-0 hole and couldn’t recover en route to a 4-2 loss to Montreal tonight at the Bell Centre.

The Bruins are now 3-7-0, the worst 10-game start by a defending Stanley Cup champion since the 1994-95 New York Rangers went 4-5-1 (they were coached by Colin Campbell — how’s that for a coincidence?).

Tyler Seguin scored a 6-on-5 goal and Milan Lucic also scored for the Bruins, who will be back in action Tuesday night at home against the surprising Ottawa Senators.
