My list of priorities:
1) Get Mitts signed long-term
1a) Find a manner to get rid of Nuke without a significant cap penalty
2) Identify a wing to replace the traded Mikko / Move Mikko
3) Get Drouin signed - preferably long-term but perhaps a bridge.
4) Get the roaring 20's line back together, and save room for an LOC raise after the season
5) Fill the 4th line with legit players. not league minimum plugs. Ultimately, the 2022 Cup may have won because Cogs and Helm fit the need perfectly ( with LOC as a key part again.)
I think the most important thing is to throw away old stale conventions about hockey. Bednar's 'system' demands it, though I don't think even he understands that. The entire bottom 6 need not be bangers. Can't the roaring 20s turn into a 4th line that plays 15+ minutes? Then make a 3rd line which looks a lot like a second line - Landy / Ritchie / Veteran looks interesting. Perhaps move LOC up and put Kovalenko in his place ( though I am unsure he brings the same defense) Then pay the first line 18 minutes of 5 v 5. plus PP. Target lines 2 - 4 for about 15 minutes each. I'd consider playing the Roaring 20s against the opponent's top line, especially with the home ice last change. Then let Mac and Mitts feast on lesser lines.
Of course, none of this works with Mikko coming back, and it sure as hell doesn't work with Mikko's next contract. Landy and Nuke are nasty unknowns, but if Landy ends up on LTIR, and CMac can jettison Nuke without cap implications, I would still move Mikko if humanly possible. I do not see any way to get Drouin resigned, get a decent 4th line ( let alone 3rd pair) and replace Nuke without moving Mikko.
What about Mikko to Carolina for Jarvis+ (Or a sign and trade 8 year Mikko for Jarvis ++) ( Or Mikko for Necas?) Boy do I wish it was possible to move Mikko and Nuke for Jarvis and Necas. We would lose the trade, statistically. But it would allow us to improve depth significantly. A boy can dream, can't he?
Drouin / Mac / ( maybe a short term Vet like Marchessault?)
Lehky / Mitts / Jarvis
Landy / Ritchie / LOC
Woods / Colton / Kovalenko
