Could The Sharks Look To Move Vanecek Or Blackwood Before The Season Starts?

With the addition of Yaroslav Askarov, could Vitek Vanecek or Mackenzie Blackwood be traded by the San Jose Sharks before the season starts? Start with why it would make sense to open up a clear path for Askarov to play a backup role in the NHL this season. Then, why division rival Vancouver Canucks would be an option for the Canucks to acquire a Sharks goalie with the injuries to Thatcher Demko and Arturs Silovs. Next, the Chicago Blackhawks' Laurent Brossoit is dealing with a knee issue and could be looking to add some insurance behind Petr Mrazek. Finally, the Colorado Avalanche have Stanley Cup aspirations. Should they be worried about the lack of depth behind Alexandar Georgiev and his poor numbers last season?
