I think he'll still be in the org for the season, there's only so many options. I just don't think he'll be a regular in the lineup because he's beyond awful and Bylsma is gone.
13th forward him and only use him in an emergency
LTIR him because there has to be something wrong with him that they can find
Waive him, he gets claimed or it's a $600,000 cap hit for the season
He retires, the $700,000 cap hit stays and I doubt he'd do it
Trade him with a pick to get someone to take him
Add him on to a bigger trade
The fantasy of him not reporting
Then it's at least league minimum for the player replacing him on top of any remaining salary. If he really needs to be gone they'd need to open up enough cap space to feel comfortable with putting him in WBS. Who knows what he'd do to WBS, though. At least try waiving him.
