They like him as a fill-in option to play with Hughes when his main partner (whoever that may be) is injured, or if they are jumbling the lineup.
He has very little flash to his game; unfortunately the scoring he showed in his draft year was a mirage. But he's a decent mobile defensive defenseman at this point, and the Canucks have a few options there now.
To anyone that hasn't been paying attention, the Canucks have been putting together some pretty solid young AHL defensive depth over the past year, and - depending on what happens during free agency - they're going to be hoping not just Juulsen, but also 1-2 of the other guys (like Hirose, Brisebois, Rathbone, Woo, Johansen, and McWard) can establish themselves in the lineup full-time over the next season.
- I personally think they already pencilled Wolanin onto the roster but none of the names listed in this post have a safe job or a guaranteed spot.
- Likewise, nobody listed is a game-breaker (Rathbone projects as a PP QB but seems to come with defensive warts as well)
The current structure provides some flexibility for the Canucks if they don't sign the multiple defensemen they are purported to be after.
