Sorry, but I got REALLY into writing this, so it's super long, and it goes into a bunch of things that weren't even brought up. Sorry for the rambling lol ^-^
First off, there's no way they're losing Spurge. If Fletcher doesn't protect the best d man on the team there will be a lot of pissed off fans, announcers, media, team-mates, coaches etc. You don't just through a top pairing right handed d man to another team without getting a king's ransom for them.
There have been rumours floating around that the team might be able to get PominP to waive the NTC, so he can be unprotected and allow another young foreword to get protected in the expansion draft. That could work if the team framed it as "we know we can make it to the WCF next season, but we need this other player here to do it. There's no chance or risk involved for you, so will you please do this to make he team as a whole better?"
Guessing Ryan White is gone (thank goodness) and I can't remember Chris Stewart's contract, but it may be up as well. Realistically it'll be tough to get everyone back, however, I think that giving Nino another bridge deal, and Granlund his big boy contract should work. Haula seems like he could be on the way out, as he wants to play more than a 4th line centre role, which could potentially allow us to resign Hanzel for another season. If that happened, that would be a filthy centre core (Koivu, Staal, Hanzal) as they're all big, strong players, all incredibly good at face offs, and tough to knock off the puck. As far as the 4th line, going to guess it's something along the lines of (depending on contacts) Schroeder-Ek/Graovac/Haula-Stewart/Tuch/Haula. Schroeder-Stewart looked good together earlier in the season, however, they aren't great puck possession players, so if those 2 were together, move Hanzal down to help that line defensively, and add some possession, and put Ek on the 3rd line.
Sorry for rambling, but I guess what I'm getting at, is hell will freeze over before we lose Spurgeon voluntarily, it might be possible to protect Coyle/Zucks, Pomminville might let himself be unprotected, and we actually have a decent amount of lineup flexibility which is great news as long as Ryan White is off this team.
Remember last season when our 4th line was greats like Chris Porter and Jarrett Stoll? Yeah, Ryan White is statistically about as bad as them, and usig the eye test he's behind every single play, trying to catch up but not able to.
