The Bruins’ 5-2 victory over the New York Rangers in Game 2 of the Eastern Conference semifinal series Sunday afternoon might have been the best of both worlds for the coaching staff.

Overall, it was a good effort. The B’s got scoring from three of the four forward lines and a couple from the defense. And they got excellent goaltending from Tuukka Rask.

On the other hand, there was an issue that should keep the Bruins grounded as the series shifts to Madison Square Garden for tonight’s Game 3 — actually, there were 16 of them: turnovers. Twelve of those turnovers came in the first two periods, and the Rangers had just one for the game. Had Rask not been at the top of his game, those giveaways could have had disastrous ramifications.

The good news is that fixing those errors is entirely in the B’s power.

“It was us. When you look at some of those turnovers, David Krejci, just inside the blue line, turns around and it’s intercepted; you could see it coming from the bench,” Julien said. “You could see the passes from our end on their sticks. A lot of that stuff was of our own doing. I think we can be better in that area, although we played a pretty good game. I think most of those things came in the second period. We just have to be a little bit better. I thought our third period was much better in regards to puck management.”

Both Rangers goals were the result of some kind of counter-punch off a Bruins mistake. The first one came shortly after the B’s had taken a 1-0 first-period lead. Brad Marchand attempted an ill-advised pass across the offensive blue line that New York’s Ryan Callahan picked off and went the distance with for the goal.

In the second period, Zdeno Chara tried to stop Rick Nash before he could get rolling in the neutral zone, but the defenseman missed with his stick check and Nash was off to the races on a 2-on-1. The play finished with Nash scoring his first goal of the playoffs.
