They need to take a page out of the Tulsky/Canes playbook (if they don't take Tulsky). Just acquire the most skilled players you can for the money you have and make it work within your system.
Surrounding the core with a bunch of guys with no talent just isn't doing it. That isn't to say you can have no Kampfs, Schenns etc. But it cant be half your roster. Kerfoot, Acciari, Kampf, Lafferty, ZAR, Engvall Jarnkrok, Schenn, Holl, Brodie, McCabe. Half the team can't make plays with the puck. Can't enter a zone with possession. Can't exit the zone with possession. Its not a good skillset for a team trying to dominate possession.
They need guys more players who can skate with the puck through the NZ, and create offense. It doesn't even really matter who. Whoever is the cheapest in contract/acquistion cost really. The Canes take all these castoffs like Burns, Gostisberge, Max Pac etc and just make it work, even though they play a dump and chase, heavy forecheck kind of game.
Dubas can stay, but he needs a change in his philosophical approach to building this team.
