As said, there are no impact defensemen likely to be available.
The forward group still needs much more than Smith and Celebrini/Eiserman/Demidov to be competitive. Right now they are a laughingstock. Come 2025, they can at best be marginally NHL quality from purely internal assets, even if everything goes right:
Eklund - Hertl - Halttunen
Musty - Celebrini - Smith
Gushchin - Bordeleau - Couture
Sturm - Bystedt - Zetterlund
Robins, Lund, Young, Coe
Something like that is the best we can do by late-2025 purely from internal sources. Unless some of these guys (or the other unnamed depth) greatly exceed their expectations, this is not a great forward group - it's a mediocre to poor 1st line, a 2nd line with a lot of promise but little to no experience, and mediocre 3rd and 4th lines.
On top of that, half of these guys will bust or disappoint at best. Without a miracle or three, we will need to add a bunch to this to get it to middle of the league standards.
Add two years to your projection - I suspect our 25-26 goal will realistically be to avoid finishing in the bottom ten.
