Edvinsson better impress because as long as he is just ok, and he is the one with waiver exemptions, he'll be sent down. That's the business part of the NHL. Maybe he impresses and gets a spot, but that would either mean 8 D on the roster or Lagesson/Holl gets waived. Yzerman will not waive AJo or Berggren for that matter. They'll either be in Detroit or on another NHL team, neither would clear. Unfortunately, if nobody gets waived or bought out, and if Edvinsson makes the team, I can see 12/8/3 as an opening night roster.
