"I thought we had a couple of mistakes there where we ended up with guys below the goal line for no reason, one right at the end of the period, which ended up costing us, obviously, and another execution one," Babcock said. "You have to clean that up.
Toronto forward Auston Matthews had a prime opportunity to tie the game late in the third period but scooped a backhand wide with at least half the net to shoot at. Matthews, who was limited to two points (one goal, one assist) in the seven-game playoff series against Boston last spring, has one goal in his past nine games.
Matthews did not talk to reporters after the game, but his comments at the morning skate earlier in the day put this rivalry between the Maple Leafs and Bruins into perspective.
"I think you look at it as another game, but obviously they've gotten the better of us so far this year," Matthews said. "It's a division game so these are important points heading into the second half of the season. I think it should be (a statement game). We should be excited for it playing a good team."
With Matthews struggling to score and No. 1 goaltender Frederik Andersen missing his seventh straight game, Toronto could not find a way to come back against the Bruins.
"Of course, we're always looking forward to playing these guys," Maple Leafs center Nazem Kadri said. "They're a great hockey team. They're well coached, tons of credit goes to them. We're a good team too and tonight I felt like we did play good enough to get a win but just didn't get the result."
The Maple Leafs get no sympathy from the Bruins, who have been forced to deal with their own struggles and injury woes. Saturday marked the first time this season that Boston's top six defensemen -- Zdeno Chara, Charlie McAvoy, Brandon Carlo, Torey Krug, Kevan Miller, Matt Grzelcyk -- were healthy enough to play in the same game.
"It's a good sign," goalie Tuukka Rask said. "We'll need all these guys in the second half and it's good to get them back.
"We've had success against Toronto, sure, but these things happen. We've lost (14 consecutive games) against Washington. I don't think it's a case of one team getting into another team's heads."
Maple Leafs fans would disagree when it comes to Boston's recent mastery of Toronto.
