NHL: 5 things to know for Tuesday night

Five Canadian teams take to the ice Tuesday night, including the surging Vancouver Canucks and the struggling Ottawa Senators.

Here are 5 things to know:

Senators in tailspin

After a 3-2 loss to the Blues last Saturday, the Senators are scheduled to play in St. Louis. But the NHL is monitoring the situation in nearby Ferguson, Mo., where police are bracing for another day of protests following Monday night’s riots. The Senators (9-7-4) haven’t had much success in their recent matchups with the Blues, going 0-3-2 since 2010-11. Ottawa’s losing ways continued on Monday, dropping a 4-3 in Detroit, its sixth loss in eight games.

The Blues (14-6-1) rebounded nicely from a tough start on their four-game road trip. They scored only one goal in losses to Boston and Montreal, but then came back to beat Ottawa and Winnipeg over the weekend. In the 4-2 win over Winnipeg, Alex Pietrangelo and Alexander Steen each had two assists while goaltender Jake Allen made 28 saves.

Canucks offence rolling

The biggest turnaround from last season for the Canucks has been the play of their offence. Sunday’s 4-1 win over the talented Chicago Blackhawks underscores that point. Vancouver (14-6-1) is averaging 3.00 goals per game, which ranks second in the Western Conference. Last season the Canucks averaged 2.33, the worst in the conference. The offensive unit is led by the top line of Radim Vrbata, along with Daniel and Henrik Sedin. Vrbata leads the team with 10 goals and has 13 points in his last 10 games against New Jersey. Daniel Sedin celebrated his 1,000th career game in the win.

The Canucks welcome back Devils goaltender Cory Schneider, who spent his first five seasons with Vancouver before a draft day trade to New Jersey in 2013. Since then, Schneider has lost both games against the Canucks — one in overtime and the other in a shootout. After a strong start the Devils (9-9-3) have gone 3-6-1 in the last three weeks.

Cardiac Flames

While the Flames (13-7-2) aren’t making life easy on themselves, they continue to find ways to win. Calgary, which has won four of its last five games, needed rallies in recent contests to pull out victories. The Flames erased a pair of two-goal deficits to beat a tough Anaheim club 4-3 in the shootout last week.

On Saturday, Calgary came back from a 2-0 deficit against New Jersey to win 5-4 in another shootout. The Flames scored twice with the goalie pulled. Calgary's league-leading five victories when trailing after two periods are one more than it had in that same scenario last season.

Beating the Ducks (13-4-5) in Anaheim has proven futile. The Flames have lost 18 consecutive games at the Honda Center. Calgary biggest focus will be on Ducks forward Ryan Getzlaf, who has scored six goals and 15 assists during a 13-game regular-season home point streak against the Flames.

Undisciplined Jets

Staying out of the penalty box has been the Jets’ biggest culprit during this currently losing slid. Winnipeg (10-9-3) has dropped four of five games, including its last two. The Jets have a penalty-killing efficient of 84.5, ranking them in the top third of the NHL. But in the last four games, that percentage had dropped to 68.7 per cent.

That could be a big problem against the Blue Jackets (6-12-2), who rank with the league leaders with a 23.4 per cent power-play conversion. Still, Columbus is on a three-game losing streak with injuries continuing to hurt this club.

Oilers in bad state

Things are bad in Edmonton. After a 7-1 drubbing at the hand of the Chicago Blackhawks on Saturday and a sixth straight loss, embarrassed fans ripped into their club.

The Oilers (6-13-2) are dreadful, especially against Western Conference opponents where they are 0-10-1. Despite the Stars 8-9-4 record, they have dominated Edmonton by winning 13 times in the last 16 contests.
