To me, realistically...
Lucic -Krejci - XXX
Marchand - Bergeron - XXX
XXX - Spooner - XXX
XXX - XXX - XXX
Chara - Hamilton
Seids - XXX
Krug - XXX
Rask
XXX
Those are the near guaranteed positions next year. Not 100% on Seids, but truly think they keep him. Some people want Chara traded, but highly doubt that happens in the off-season too.
Connelly and Pasta fill out 2 of the XXX's, also guaranteed.
Eriksson and Smith, potentially fill out the next 2 top 9 XXX's. But this off-season, I'd be looking for new options if possible. Altho, Eriksson>Smith for now. Altho, I wouldn't give away Smith. He gets another year to get his **** together before would trade him for little.
Campbell, Paille, Svedberg and Bart can walk. Soderberg too, but if he offers to stay at a welcoming hometown discount, may not be able to resist.
Kelly, traded or bought out. I would suck it up and buy him out if no one truly wanted him.
Try and resign, McQuaid. If he doesn't come fairly cheap, use Miller as his replacement. If does sign, Miller as the #7. And no matter what, like the Bruins to try and bring in a top 4 defenceman. #1 priority. Get another defenceman, Miller picks it up, Tortman/Morrow making a push, Seids would then be the odd man out. Maybe Chara too, depending how the season moves along.
Also, need to find a competent backup goaltender. Rask needs to play 60 games, not 70.
That would be my game plan going into next season.
Would also get rid of Claude. Guy did well overall as a coach here, and once he's gone, will mostly remember the success he achieved here. Just time to move along, coming of a new era.
Defence being the biggest obstacle, but this team can still compete for years to come.
