Getting away from the TD Garden seemed to help the Boston Bruins as they exploded for six goals in their first victory of the season. Here are a few things we learned from the Bruins’ 6-2 win over the Avalanche on Wednesday night.

…Jonas Gustavsson’s capability as backup goaltender.

The Bruins went down to the last days of the preseason before naming Jonas Gustavsson as backup netminder to Tuukka Rask. The 30-year-old Gustavsson — 3-3-1 and a 2.56 GAA last season with Detroit — was named starter for the fourth game of the young season — first on the road.

“He could really make an imprint when they need it most,” NESN analyst Andy Brickley said pregame.

Gustavsson did just that, especially in the first period when Zdeno Chara took two for hooking Jarome Iginla just 31 seconds in. After killing that penalty, the Avs would take up shop around Gustavsson for a good minute before Kevan Miller and Jimmy Hayes put Boston up, 2-0.

“He gave the Bruins everything they needed tonight,” Brickley said with three minutes remaining about Gustavsson’s 20-save performance.

…The captain is back.

After getting injured early in his first preseason game, Zdeno Chara was “day to day” until Monday’s first start against Tampa Bay where he logged 21:27 of ice time. In Wednesday night’s first period, Chara’s 7:45 was second to Torey Krug and Adam McQuaid, while assisting on both Boston tallies. The Bruins captain would end the evening with a team-leading 24:12.

…Hayes making the transition.

Newcomer Jimmy Hayes from nearby Dorchester, Mass., entered the game a minus-5. The former Florida Panther and Boston College star, swapped for Reilly Smith, had four points. He scored Boston’s second goal before assisting on Chris Kelley’s goal – Boston’s fourth; then on Ryan Spooner’s first of the season and Boston’s fifth; and finally David Krejci’s open-netter with 1:29 left.

“Bit of a slow start,” Brickley said during the game about Hayes’ play the first three games. “But he’s all over the ice tonight.”

…The kids came to play.

Colin Miller was playing his second NHL game; Tyler Randell and former Boston College and Hartford, Conn., native Tommy Cross made their NHL debut. Randell scored the Bruins’ third goal while playing 8:53 with a plus-2.

Miller and Cross combined for 29 minutes and a plus-1, despite coughing up Colorado’s second goal by John Mitchell at 11:20 of the third period.

…How effective the blue-line iron can be.

Chara, Kevan Miller, Krug and McQuaid averaged 22 minutes with a whopping combined plus-9

…They found some team defense.

“Gotta find their defensive game,” NESN analyst Barry Pederson said pregame about a must-do against Colorado.

The Bruins did just that, holding the explosive Avalanche (10 goals in their first two games) to six shots each of the first two periods; the last a power-play goal by Gabriel Landeskog.

…What pressure?

“No pressure at all,” Torey Krug told NESN just before the first faceoff Wednesday night about needing a first win of the season. “Makes it more fun.”
