Yep.
Even though the team likes Broberg, I think Samorukov takes the #6 spot this fall. Doesn't hurt his chances that he fills a need/complements the other 5 main defencemen better. Plus Broberg, Niemo, Desharnais are all wavier exempt, so there's no risk to sending them down.
How I see the defence at the moment...
Nurse-Bouchard
Kulak-Ceci
Samo-Barrie
The left side's pecking order is clear, though the entire right side is fluid imo. I could see all of the RHDs playing on any of the pairings. Only clear part is Ceci's pairing is going to be the shutdown one. so I think you start him with Kulak for some stability, but then swap in Samo (or Niemelainen) once he gets comfortable at the NHL level.
If they can figure out the cap, I also wouldn't be surprised to see the Oil break camp and play with a 11-7 set up again.
