Depends on who they get as coach. I don't see a major overhaul.
Lynn would be a great fit and less likely to see a major overhaul. He has the pieces, but does he really want to coach for this owner and this FO?
Again, the FO and owner say there's no "dysfunction."
However, looking outside the box, this team looks like a horrendous opportunity and a career ender for any HC.
Things need to change, mostly to show any candidate coming in that this is a great opportunity to evolve their career.
