The bottom6 needs a big change if this team wants to seriously contend for Stanley Cup.
Forwards you let go:
Chiasson; PP specialist, nothing else.
Khaira; He has been part of one of the worst bottom6 for years. He is not going to be solution to get better. Horrible numbers every year.
Shore; Bad player. Doesn't help one bit.
Kahun/Ennis; One you sign, other you let go. 3LW spot.
Nygård; Can skate, but can't do anything else at NHL level.
Haas; I have kinda liked his game. Would sign him over Khaira, but upgrade shouldn't be that hard to get.
Forwards you re-sign:
RNH; not the greatest year for him, but the team can't cut quality players when it is lacking exactly that.
Yamamoto; see above.
Ennis/Kahun; Should be a cheap deal.
Try to get rid of Turris, Neal and/or Kassian. I would send 1st round pick with Neal or 2nd round pick with Kassian for Seattle if agree to take either one.
On defense you also need more skill and less "glass'n'out" players. I would throw big money towards Hamilton, but that is unlikely scenario. I am not fan of Larsson. Doesn't really understand what many see in him? He is one dimensional defender who isn't even that good at suppressing chances against. Actual elite defensive defenseman help their team to out-chance and out-score opponents by not allowing chances against. He is decent in defensive zone, but he spends way too much time there. Definition of a 3rd pairing defenseman that gets out-chanced and out-scored, without a good partner. Doesn't really move the needle. If he gets resigned he should be paid accordingly to what 3rd pairing guys get. No way I give him over 2 year extension and needs to take pay cut. Has history with bad back also.
Barrie is one dimensional too, but with the opposite skill-set. He has skills that team lacks, more than Larsson but on the other hand Bouchard should be getting minutes and they provide same qualities. Would re-sign him over Larsson, but something like 3x4. If that isn't enough then let him walk. Don't understand the hate that Bear gets. He is the only that can really push the play and out-chance opponents. People don't realize how much good things he does on the ice. Defends the blue line well, that forces opponent to dump the puck and can move the puck well. Those are traits that team lacks and why they spend too much time defending. Kulikov is unknown at this point.
Nurse-Bear
x-Barrie/Bouchard
Jones-Bouchard/Larsson
Lagesson/Russell
Driedger would be my target also. I am fine with either Koskinen or Smith as a back-up, shouldn't make or break the team. But not a fan if they buy Koskinen out. Rather trade with retention.
