Let's take a look at the team over this year and the following ones, excluding depth pieces.
LW:
Hyman - 2 years then UFA
Mikheyev - 1 year then RFA
Johnsson - 3 years then UFA
Engvall - 1 year then RFA
I'd be very surprised if we don't find a way to extend Mikheyev and Engvall. That gives us four players that can play top nine, with Kerfoot and Willy able to transition over and Moore who can play in a pinch. There's enough talent and there's good depth. There's also Robertson coming in a couple of years. All in all, we are well situated now and in the future.
C:
Matthews - 5 years then UFA
Tavares - 6 years then UFA
Kerfoot - 4 years then UFA
Spezza - 1 year then UFA
This is a strong group. Kerfoot is good in the #3C spot but Spezza can also hold down that position. In case of injuries, Willy is also able to take a spot here. We have a bit of quality depth issues here, but nothing that can't be solved by a restructuring this year. We'll need to find a new Spezza for next year though. There's also enough term that no particular additions need to be done for at least 4 years.
RW:
Marner - 6 years then UFA
Nylander - 5 years then UFA
Kapanen - 3 years then RFA
Top-end talent is great but the depth isn't ideal. We have a couple of players who can fill in on the fourth line, but not a lot of options that I'm comfortable moving into the top nine. However, I believe both Engvall and Mikheyev can move over if necessary, and the LW side could handle that. There's also Bracco, as a bit of an unknown. So the current situation is fine, and all of these guys will likely be around for a while. It'll do.
LD:
Rielly - 3 years then UFA
Muzzin - 1 year then UFA
Dermott - 1 year then RFA
Sandin - 3 years then RFA
Here things start to get interesting, however I think we're still in a good position. There's the possibility to re-sign Muzzin if we can get him on a very short term, but the other three should be around for at least three more years and that's a group I'd be very comfortable with. Depth is an issue from next year and forward, but right now we're strong here.
RD:
Barrie - 1 year then UFA
Holl - 4 years then UFA
Ceci - 1 year then UFA
Liljegren - 3 years then RFA
This is still a weak area. Barrie is a terrific player for an offensive spot, and Holl is establishing himself as a second pairing option. Liljegren coming up helps. However, Barrie is gone after the year, leaving us with two options even with Liljegren. So we're relatively weak here right now, and we're in trouble next year. There's a solution there though since we have Holl and Liljegren under long-term control. If we re-sign Muzzin, it allows us to move someone over to this side. Otherwise, one player with term will be needed, the sooner the better, and we also need improved depth here.
G:
Andersen - 2 years then UFA
We have a solid starter and two #3 guys. So the depth is lacking already, and there's no immediate option next year. This is the position that will make or break us long-term. If Scott or Woll pans out, we're golden. If they don't, we're in big trouble. I want to stress that we shouldn't re-sign Andersen. He's already at an age where goaltenders generally decline, he'll command a huge contract, and those tend to be the worst contracts to give. Unless he's willing to give us an unprecedented short term for a guy with his profile, he should be let go.
Conclusion:
An upgrade at RD would be preferable, but it needs to be someone with enough term to help us long-term. Otherwise it's a band-aid. A real backup goaltender wouldn't hurt either, but the real target here should really be a #1B option. It would give us strength at the position while allowing transition towards the next starter in Woll or Scott, or give us time to find something else.
The most expendable asset with value would be one of our LWs, and my preference there might be Johnsson. Engvall won't cost much to extend, and with the injury to Mikheyev I'm guessing that he won't command a big contract compared to how good he is either. There's also Bracco, who supposedly have some good value. I'm not sure the organization believes in him as a long-term top nine option, otherwise Kapanen could be available. Especially given the talk that some teams absolutely loves him.
There's another option that might be worth exploring, and that might be very controversial. The player that in my opinion holds the most value on the market compared to quality is Rielly. If we extend Muzzin, we could still roll a strong trio on the LD, and Rielly would bring in a huge haul. With two years remaining, I'm expecting that we could acquire an absolute top flight RD prospect, or something of a similar value. That could give us three long-term pieces on the RD, while Muzzin buys Sandin and Dermott time to solidify the top four.
If Johnsson could bring back a solid #1B with term or RFA status, and we move Rielly in the summer for a high-end young RD, I'd be very comfortable with essentially every single position now, next season, and going forward. It would be even more youth, but I think we'd be talking about a lot of guys who could come in and make an immediate impact. I'm not counting any surging prospects here, but I also don't count any unexpected declines either so I think it evens out.
