Nothing wrong with Dunlap or Atkins IMO. Together they're half of a dominant defensive line. It's the other half that needs to step up, and I think it could if given the chance.

Bengals don't need much as they've now got one of everything in their Dline room. Shut down and replace MJ would make a massive difference IMO. That's 40-60 snaps per game. Draft Ed Oliver and start winning on the edge again. Rebuild the run defense around a young player who is a TFL machine.
