I suspect that Hertl, Meier, and Eklund will be legitimate top six forwards in 25-26. Bedard/Fantelli/Michkov likely will also be. We'd have to fill in two spots, but hopefully we can get one or both of those internally - someone we already have (Bordeleau, Gushchin, Bystedt, Lund) or another high-quality draft pick (2023 late first, 2024 first). Getting a decent 3C (maybe Couture/Bordeleau/Bystedt) would also be important, but we may have a legitimate forward core.
Defense is harder - we'll likely have Karlsson and Ferraro, but neither are top pairing defensemen now and won't be in 25-26. Internally, we don't likely have a top pair defenseman - Merkley, Knyazev, Laroque, Havelid, all likely top out as second pairing if they do succeed. It's not impossible, but we need to find a legitimate top pairing defenseman somehow and it seems unlikely we'll draft one who will be ready by then.
We have plenty of goaltending lottery tickets, so I don't see a reason to worry about them.
I think playoffs in 25-26 is a very realistic goal, and should be the medium-term goal. We could be a playoff team in 24-25, too. I do not see that happening this year or next year, no matter what we do.
