Keep Faulk, AVs need long-term help. Faulk has 2 years remaining on his contract and will leave before the AVs turnaround is complete. Canes have missed the last 7 years of playoff contention; with constant losing it hurt the fanbase where they're easily the worst in the NHL with 66% capacity of 11K per game. Duchene can help make the team competitive, otherwise, keep losing and eventually the already small fans will stop[ attending games.
Francis is not going to do a quick fix. He's building the team to be competitive for years. I don't see him trading 19 year old Hanifin for 2.5 years of Duchene. There's no 100% guarantee that Duchene will resign and honestly if I were him, i'd hit the market and cash in. He'll get a lot more money hitting free agency than staying with the Canes.
As much as it would pain me, cause I do think Hanifin is going to be a legit top pair defenseman, I would seriously have to consider a deal around Hanifin and Landeskog.
Slavin, I think we can safely say he is 100% untouchable.
