It's not so simple, his next contract is a major decision point for the Ducks, do they consider him a core piece and will give him the contract he'd demand, or do they then trade him, most likely for multiple lesser pieces. Especially if another team does see him as a C and is willing to pay up for him.
Ducks have plenty of cap space and decided to punt on the decision for 2 years, which is why the discussion is largely silly, but it is notable that they bridged him and seemingly don't consider him a C long term for them.
Edit: It's basically the Necas situation, where he's likely being traded next offseason cause he's not a long term Cane and wants to be a C.
