Sorry for the terrible format of this post in advance.
I'm staying firmly adamant about this team having a good, new "core" in place moving forward. I don't think a complete blowup is necessary, but a re-tool is a definite must. Look at what we have:
Stepan, Hayes, Lindberg, Miller, Kreider, Fast, Hrivik can all serve as the nucleus going forward of our young forward group. Brassard and Zucc are still productive, in their prime, and have team friendly contracts considering what they provide. Buchnevich is a wild card at the moment, but I'll give him very mild expectations and say he can be a 30-35 point 3rd line winger next season. Tambellini and Nieves seem poised to have good years in Hartford next season, maybe Fogarty as well. We have Gropp and Kovacs that look like they'll be good 3rd line wingers with some more potential than that to be added in the next two or three years. I'll leave out Stromwall because I literally have no clue how he'll translate to the AHL level, but he looks like he has some potential as well.
Brassard, Zucc, Stepan, Kreider, Miller are 5/6 of your top-6 next season.
Lindberg, Hayes, Hrivik, Fast, and Buchnevich (assuming he'll get NHL time next season, like I said, going with very mild expectations of him so I don't over-project him) are 5/6 of your bottom-6 next season. So saying we trade Nash, lose Staal, Stalberg, and hopefully move Glass, you're looking at a skeleton outline of:
Kreider-Stepan-?
Miller-Brassard-Zucc
Buchnevich-Hayes-Fast
Hrivik-Lindberg-?
Not a terrible core going forward. A Nash trade should net us a piece to add to that group. I'd honestly bring Stalberg back as insurance if Fogarty/Nieves/Tambo can't crack the NHL in two years.
The defense has McDonagh, Skjei, Klein, and McIlrath to build around. Keep Yandle. Figure out what to do with Staal and G. Keep Staal if you have to, he at least has shown he's still capable and you don't want to throw Skjei and Dylan both into the fire next season. Let Staal serve as your insurance minute-eater when necessary, and move on from G. Shattenkirk would be nice, but I don't see it happening. Skeleton outline again:
McDonagh-Skjei
Yandle-Klein
Staal-McIlrath
Hank
Skapski/Hellberg/Raanta
Shestyorkin looks like he's gonna be a good goalie. Halverson too. Hank serving as a mentor to these two will be critical to their development when they're slowly replacing him in the next 4-5 years.
Are we really that screwed in the future? Down the road when Stepan, Kreider, Brass, and Zucc are older? Maybe, that completely depends on our recent draft picks panning out.
But for now, I don't think we're that terrible going into next season.
