Agreed.
Depends on who is acquired with the 1st round pick. And Hronek is injured. Hopefully he'll be given a clean bill of health and fan can get to see how he fits in, if he does, with the team.
Over the long haul, the defense will revert back to being middling, if not worse, regardless of systems. Moving on from Myers will be huge. I think having two offensively minded defensemen might be risky. Both Hughes and Hronek would be better served by each being paired with a responsible defensive defenseman, with size preferably. I think having Demko back has also made the defense look better. We'll see.
