"Well, again, it took us a while to get going," said Julien, postgame, on Saturday. "I thought that the other team played a pretty solid game.
"They were strong on the puck, they were solid, they were gritty, and we were a little light on our sticks there for the first 40 minutes.
"That kind of put us in a bad situation," said Julien.
Julien said that talk of an emotional letdown after the B's 7-0 drubbing of Montreal on Thursday "would be a weak excuse.
"We’re certainly not going to use that as an excuse," he repeated. "This is the time our year where you got to make sure that you’re able to push those games aside.
"There’s a lot of emotional games coming up in the future here, in the near future, and we’ve got to be able to respond night after night.
"It was more of [the Bruins not being] as good as the other team tonight as far as the will to win those battles early on and being heavy on the stick," he said.
Asked if the B's were a little to determined to make harder plays, rather than take a simpler route to a scoring chance, Julien agreed that Boston was forcing their plays.
"That’s a good assessment," said Julien. "I think it’s that we didn’t get pucks in deep and we didn’t get our feet going early enough.
"That’s where we had success the last couple games. So we forced a lot of things and consequently our top line didn’t have a shot after two periods.
"And you know that when those kinds of things happen, we’re not doing the things that we should be doing," he said.
However, Julien also said that the short turnaround between games could help the B's in the long run.
"Yeah, that’s often a good thing," said of the 30-hour difference between start times. "We don’t have time to dwell on this one here.
"You've got to turn the page. You win the big game tomorrow in Philadelphia, and you’ve had a pretty tough week against some pretty good hockey clubs.
"If you can come out of the there 3-1, with the week, it’s been a pretty good week. So that’s what we’ve got to focus on," added Julien.
"Let’s turn the page on this one here and hopefully be a better team [Sunday]," he said..
