Next year we'll have McLeod and Maksimov joining Bakersfield's forward core.
Benson/Marody/Currie
Gambardella/McLeod/Yamamoto
?/?/Maksimov
I think ideally you have one of Currie, Marody, or Gambardella with the Oilers next season in a depth role making room for Maksimov on a skill line.
Then you have Samoroukov and one of Bouchard/Persson (and maybe Berglund) joining the D-core.
Jones/(Bouchard or Persson)
Lagesson/Bear
(The collection of Lowe, Stanton, Day, and probably other players I'm missing.)
/Samoroukov.
Guessing Samoroukov starts in the ECHL because Bakersfield has too much depth. In the NHL, we have:
Klef/Larsson
Nurse/Russell
Sekera/Benning
Persson
I think Manning gets waived, adding to the depth of Bakersfield. Benning is an established 3RD. My thinking is that Bouchard starts in Bakersfield, gets top pairing minutes and 1PP duties. I think it would be ideal to develop Persson in Bakersield, let him get acclimated to pro hockey on NA ice. Is that what he would want though? He cares about his own development, wanting to take it slow and spend another season in the SHL. If he truly cares about his development, I think he'd be okay spending some time in the AHL.
I think we're stuck with that NHL D-core next season. You probably could trade Russell, but that would just open up a hole at 2RD. You'd be hard pressed to find a team wanting Sekera's contract with his injury history. If he proves to at least be a 2LD again, maybe he'll become trade bait.
Takeaway: The farm team will continue to be strong next year, and in the 2020/21 season we'll have an influx of prospects making cases to join the NHL squad.
As for the goaltending situation... Montoya walks obviously. Let Starrett be the starter in Bakersfield next season. Hawkey comes in as the back-up, bumping down Skinner to ECHL. Sign a stopgap back-up for next season in the NHL. If Starrett continues to be consistent next year, he earns an NHL back-up job. Skinner and Wells compete for the AHL back-up job when Starrett is called up. The following year, Skinner and Hawkey compete for the starting job, and Rodrigue/Wells compete for playing time in the ECHL. That's goalie depth.
