They're in rough shape. One of those teams where the obvious thing to do - getting younger value back for Kane, Seabrook, or Keith even - is painful, difficult and unpopular. Oh well, three Cups is an amazing legacy to rest on for a while.
Don't all 3 of those players have full NMC's?
Seabrook and Keith are in their 30's and declining (to different extents) have long and expensive contracts. They'd get about as much as Parise would in trade, if they'd accept it.
Kane as good as he is, still has a $10.5m cap hit attached to him. I don't think he'll fall off a cliff, but be has 900+ NHL games played and 18,000+ mins ToI, and he's not even 30. That is a lot wear and tear over the years.
The Saad for Panarin trade hasn't worked out well for them either.
They are an older core with expensive contracts, but thy are also playing half a dozen guys on their ELCs.
Hossa probably gets shipped out to a cap floor team. $5.3m cap hit, but only $1m in salary for the next 3 years. He has a NMC, but what will he really care if his playing career is over?
