"We want to create a culture where everything is earned," said coach Travis Green, who was hired April 26 to replace Willie Desjardins.
The additions also provide better depth, something required to play the up-tempo style Green wants to play.
"I want energy in our game," said Green, who coached the Canucks' American Hockey League affiliate for the past four seasons. "Anyone that watches hockey closely sees how fast the game is now, and when you talk about playing fast, players just don't skate fast and not get tired. It takes a lot of energy to play that way, and teams that play the fastest have quite a bit of depth. You need to have a fourth line you can play and not hide and just play six or seven minutes."
Vancouver tied for 24th in goals against last season (2.94) and scored the second-fewest goals in the NHL during the past two seasons (two ahead of the New Jersey Devils).
It is counting on bounce-back seasons from Daniel Sedin (44 points; 15 goals, 29 assists) and Henrik Sedin (50 points; 15 goals, 35 assists). But with a 37th birthday before the season, even the twins know their days of winning scoring titles have passed, so Vancouver also needs more from Eriksson, who had 24 points (11 goals, 13 assists) in 65 games, his lowest output since his rookie season of 2006-07 with the Dallas Stars.
