I wanted the habs to offersheet Nurse 2 years ago when Edmonton had no cap space. They could have had him for possibly a 2nd round pick, or a 1st and 3rd.

They missed the boat, Nurse isn't worth Drouin, Mete, and a 2nd. That's a bad trade for MTL. They have Romanov, Struble, Norlinder, Harris... better off waiting for one of them to be ready than overpaying for a guy like Darnell Nurse.

In that case, what 1st left defenseman they should target by a trade which imply Domi or Drouin (a choice has to be made here and i pick to trade drouin cause he's signed for a couple of years and still have potentiel but domi fits more in DNA of MTL spirit and have more potential than drouin i think.), If you look into this we could be contender real soon with a great backup goalie and first left defenseman. Tatar will be resign to long term cause he loves playing in mtl and love the city plus he produces a lot so you cant have all theses player in your lineup.

In this case your forward lineup could look like this in couple of years:
1st line : Tatar - Suzuki - Gallagher
2nd line : Domi - Kotkaniemi - Caufield
3rd line : lekhonen - danault - XX
4ht line : XX - poehling - evans

I know you have to pay to receive which is why i think an early 2nd pick, drouin (who still have potential) and Mete (good potential too but not on a first pair) could land a top 2-3 guy and this is a big missing part in montreal on the left side since markov departure. I think montreal wont suffer too much in a long term for trading this package because nothing garanty us that drouin will become a top forward but he could be on the wing of Mcdavid and be damagable more than in mtl lineup. Yes, Mtl have great rookie but it will take time and you have a window now with price, weber, petry, gallagher, and tatar.

I would be going after Sergachev. Tampa Bay doesn't have much cap space to defend against an offersheet. Sergachev might sign a $6.340 × 2 years deal hoping TB will match. I would expect TB to match, but they would have to move salary to do so.

Maybe TB would talk trade with a team before it goes to an offer sheet. Maybe they would take Mete ++ for Sergachev. Would have to be low salary players to work for them. Mete, Poehling, and a pick?

I would go the offersheet route, if it works great, if not you go with:
Romanov - Petry
Mete - Weber
Chiarot - Scandella
Marchenko

I would try trade Kulak in a package to Detroit for Bernier to backup.

I don't think MTL needs to trade either of Domi or Drouin yet. I would be trying Drouin - Domi - Gallagher as first line next year hoping Gallagher can get those two guys going, if he can't no one can time to move on.
