The Vancouver Canucks have improved their roster by adding speed up front and size to the blue line. Despite the team's size, they are lacking a puck-moving defenceman in the bottom two pairings. With $1.015 million in cap space, the Canucks can sign a free agent. Here are three options:

1. Kevin Shattenkirk, a veteran right-shot defenceman with Stanley Cup-winning experience. Coming off a $1 million deal with the Bruins, he could be a good fit for the club.

2. Justin Schultz, a right-shot blueliner with Cup-winning experience. Vancouver could target this Kelowna native to add a solid puck-moving skillset to their blue line.

3. Calen Addison, a young unrestricted free agent with offensive abilities. Despite struggles on defense, he could benefit from the coaching staff's guidance and development.
