While it's possible I just don't see why people keep stating that with certainty.
It's already a low % of the cap and likely to end up being 4-5% instead of 6+. And he's not a heavy producer, he shouldn't experience a drastic falloff mentally, and his contract is the current going rate fo ra 3C, never mind an elite 3c. Even if he ends up an average 3rd liner for 5% of the cap, I don't see how that 'hurts' anyone, and I'd argue it's much more likely he remains a strong option.
I'm still seeing a lot of people (not you, just musing aloud) that seem completely unclear about the kind of player Danault is, but I'm guessing he erases some of that worry 10-20 games in. He already hit the ground running.
