There’s nothing wrong with the Vancouver Canucks’ offence that their defence can’t fix.

The lack of goals by Canuck defencemen is one of the biggest contributing factors to the National Hockey League team’s worst regular-season scoring crisis in seven years.

“When we’re scoring as little as we have — six goals in the last five games — the defence definitely shares that burden,” blue-liner Kevin Bieksa said. “We have to pitch in. It’s not a matter of not getting the chances; it’s a matter of bearing down and scoring. That’s all it comes down to. We’re not going to blame (the forwards); we should be pitching in, too. That’s no secret.”

Everybody knows the Canucks, like many teams, count on their defence to provide vital secondary scoring. What isn’t so well-known is just how reliant the club has become on its blue-liners to contribute goals.

For at least a decade, stretching back two earlier coaching regimes, the Canucks have had one of the most active and offensive blue-lines in the NHL. In the last four years, Vancouver ranked second in goals by defencemen three times, and finished fourth once among 30 teams.

Last season, when the Canucks’ team offence plummeted to 19th in the NHL from fifth in 2011-12, the goal rate by Vancouver blue-liners actually increased slightly to 0.58 per game from 0.5.

Jason Garrison and Alex Edler co-led Canuck defencemen with eight goals each during the 48-game season. Bieksa scored six times, Dan Hamhuis contributed four goals and the defence amassed 86 points on a team that scored just 127 times.

None of the individual scoring totals were exceptional, as the Canucks’ top four defencemen have proven themselves to be offensive contributors in the NHL. It’s partly why Edler, Garrison, Hamhuis and Bieksa are being paid $19 million US this season.

Their scoring is not a bonus to the Canucks, but a necessity.

But as Vancouver hung on to get a point Tuesday in a sloppy 3-2 shootout loss against the Florida Panthers, scoring more than once for the first time in five contests, Garrison’s goal famine reached 21 games and his pointless streak 13 games.

Edler hasn’t scored in 14 games and has just a single point in 12. Bieksa’s goal in last week’s 2-1 loss to the San Jose Sharks is his only one this season. Hamhuis went a 12-game stretch in October with only one point, but has three goals and an assist in the last eight games. He is the only Canuck defenceman who is scoring.

As a group, the blue-line is still ninth in the NHL with 10 goals, but four of those were scored in the Canucks’ first four games. In the last 19 games, Vancouver defencemen have scored just six times — barely half the scoring rate from last season.
