TORONTO — Momentum is mass times velocity. The Bruins believe that’s all it is.
With the Maple Leafs  having forced Game 6 but the Bruins playing a strong third period in their Game 5 loss, one question that came up a bit from the Toronto media Sunday was which team has the momentum in the series, and how big a factor it is.
“I don’t know if there is such a thing, honestly,” Claude Julien  said after Sunday’s morning skate. “When you’re in the playoffs, whether you win or lose, you turn the page and [focus on] the next game. As a losing team, you have to bounce back. As a winning team, you’re trying to keep that momentum but you know that there’s going to be some desperation from the losing team.”
Julien made the point that if momentum was as big a factor as people like to believe, you’d see sweeps after one team won a game, but that there was only one sweep in the first round (San Jose over Vancouver) in the first round.
While momentum can definitely be played up a bit too much, it’s still a factor and something the Bruins could give the Leafs if they don’t end the series Sunday. A Game 6 win would give the Leafs two straight wins and a whole lot of confidence that was built with their backs against the wall.
Yet the B’s don’t want to acknowledge it as such. While they can’t explain why they came out flat in Game 5 against the Leafs, they don’t think either team wouldn’t have reason to come out as hard as they can in Game 6. They view a win as a win and a loss as a loss, and every playoff game as one worth showing up for.
“To me, the next game is the next game,” Chris Kelly  said. “Momentum, a lot of times, is just a word. It depends on who’s playing their game that given night.”
