According to Dhaliwal, the team may look to move a young player for help up the middle, and if that involves moving a talented right side defenseman, they may need to bring back Juulsen as depth, and as a result, they don't want him talking to other teams.
On the surface, this may look bad for Vancouver, but this is a move simply done because the team like Juulsen and potentially would like to keep him in free agency, and with the team eyeing centre help, they could be a team to watch heading into the summer.
