We have 14 F ($51,377,499), 5 D ($18,400,000) and 2 G ($8,750,000) under contract next season with a total cap hit of $78,527,499. That gives us just under $3M to work with. If you trade Allen for futures and replace him on the roster with Husso, you're up to just under $6.6M in cap space and the same roster count by position. Even if you sign Dunn long term for $5M (and I'm not convinced he will ever be worth $5M) you still have over $1.5M in cap space with 14 F, 6 D and 2 G.
Maybe I'm looking for a unicorn, but at this point I consider trading Schwartz ($5.35M) for a Top 4 D to pair with Faulk (leaving Scandella-Parayko as the shutdown pairing) that has a cap hit of $6M or less. Cap-wise, that leaves you with over $800k in space and 13 F, 7 D and 2 G. At that point, you may or may not add the 14th F to the roster to fill it out, and you still have all of ROR, Tarasenko, Schenn, Perron and Thomas in your Top 6 F group. You've got your D pairings set, and you're looking for one of Sanford, Blais or Kyrou to claim the final spot in the Top 6. You also still have two of those players plus Bozak, Steen, Sunny, Barby and Mac Mac to round out your 3rd and 4th lines.
The biggest question is - who can we land with Schwartz as the bait to slot in as the 2LD alongside Faulk -and- who has a cap hit of $6M or less next season? Just spitballing some possibilities outside our division...
- Lindholm from ANA? Sonny Milano and Max Jones are the only two natural LW on the Ducks.
- Oscar Klefbom or Darnell Nurse from EDM? I'm sure Schwartz would fit nicely alongside McDavid or Draisaitl.
- Vlasic from SJS would be an interesting option to revive his flagging career here, but the Sharks would have to retain at least $2M-$3M a year (unlikely) for me to have any interest in the last 3 years of his deal.
- Edler from VAN? He has the experience, but I'm not sure he has the wheels left to be what we would need him to be. I'd want a prospect like Jett Woo and/or some salary relief in the deal.
- Brady Skjei from CAR?
- Ryan Murray from CBJ? I would need a sweetener for him.
- Nick Leddy from NYI? I would need a sweetener for him, too.
- Dmitry Orlov from WSH? Seems unlikely they would be looking to add a Top 6 LW but youneverknow.
- Michael Matheson from FLA?
- Ryan McDonough from TBL? They would have to retain at least $750K and move another F to make room for Schwartz but Tyler Johnson is the only natural LW on their roster signed for next season.
So not a ton of great options there, but you also have to keep in mind that there are a few UFA LD options available like Torey Krug, TJ Brodie and Dmitry Kulikov who could be signed after you've traded Schwartz for a nice futures package. I think that is less likely in the flat cap environment but it certainly can't be ignored.
TL;DR - There are a ton of possibilities to have a decent-to-solid Top 4 without Pietrangelo coming back, but I don't see where it can be argued that our best option to stay a Cup contender is to get 27 back in the fold.
