Let's do a quick update on the team from the first post, which essentially represents the boring version of what next years team probably looks like:
Johnsson-Matthews-Marner
Hyman-Tavares-Nylander
Mikheyev*-Kerfoot-Kapanen
Robertson-Engvall-Barabanov
Rielly-Dermott*
Muzzin-Holl
Sandin-Liljegren
Marincin
Andersen
Campbell
Everyone in this line-up has a contract except for Mikheyev and Dermott. There's $2.7mil in cap space to split between the two. Let's say they both get pushed into short-term $1.25mil because of the flat cap.
That gives us $200k in cap space with a 21 man roster. No Spezza, and our defence looks kinda not great.
There's of course ways to create cap space here. With Robertson's emergence and the depth that provides on the left wing, a Johnsson trade feels pretty inevitable. So let's pop him out and replace him with Spezza (or someone else, but let's say Spezza) at $700k.
That gives us a 21 man roster with $2.9mil in cap space. We could do two things with that: sign Mikheyev and/or Dermott to longer and slightly more expensive deals. Or we could still strong-arm them into cheap deals and use the cap space to do something with our defence. One of Marincin or Liljegren would get bumped off the roster (other being the 7D) so that gives us about $3.5mil to spend on a (preferably) RHD.
There's still two more fairly simple ways to create some more space. First would be trading Dermott. The reasoning here would be any defenceman we sign would probably take that RHD spot alongside Rielly so Dermott would get bumped down to the 3rd pairing and ideally Liljegren is ready to take that role at a slightly reduced price. The second would be moving Kapanen and hoping that Barabanov is ready to take that role at a reduced price. Doing so would give us a line-up of something like this:
Hyman-Matthews-Marner
Robertson-Tavares-Nylander
Mikheyev-Kerfoot-Barabanov
Engvall-Spezza-Korshkov
Rielly-______
Muzzin-Holl
Sandin-Liljegren
Marincin
Andersen
Campbell
That roster has $6.4mil in cap space available for that RHD who is either signed in free agency or acquired from the Johnsson/Kapanen/Dermott trades. The cap space could go up or down slightly depending on if Petan or Agostino or Brooks takes that last forward spot instead of Korshkov, or if Lehtonen takes the 7D spot instead of Marincin.
Ideally, that defenceman doesn't come in at more than $5.5mil because then we could also have enough cap space to carry a 13th forward through what will likely be a pretty compressed schedule.
So TLDR there is a route to acquire another $5-6mil type defenceman that doesn't require us to blow up the top-4.
