Yeah if Landy does indeed return, the writing is on the wall for Girard or Byram essentially... Maybe Manson.
The good news though, is they have all the main positions signed in those 15 playrers... You're looking at:
Landy - Mack - Mikko
Lehky - RyJO - Nuke
Wood - Colton - ????
LOC - ???? - ????
Toews - Makar
Byram - Manson
Girard - ????
George
???
You know, Byram's $3.85m caphit is an interesting number given that it's pretty much the amount that would need to be freed up to make the roster work next year...
Below is a projected 21 man roster without Byram, which has $1.5m in capspace.
Essentially, if you can trade Byram for an ELC forward/center (who can be added anywhere in the lineup bumping others down as necessary) you'd be rolling with a 22 man roster and ~$500k in capspace which would be a good amount to have for cap acrual purposes.
Landeskog - MacKinnon - Nichushkin
Lehkonen - RyJo - Rantanen
Wood - Colton - Kovalenko
Olofsson ($775k) - Pavel - O'Connor
Toews - Makar
Girard - Manson
Behrens ($925k) - 6D $775k
7D $775k
Georgiev
Annunen/Prosvetov $775k
Now obviously opening up Manson/Girard/Lehkonen's capspace would free up more cap than Byram, but Byram's number would be enough if they wanted to go that route - so long as you can find decent $775k guys for depth roles.
Not saying I would trade Byram, just that you could make the cap work by moving only him if you wanted to go that route.
