I think they are in a bad situation: if the keep Fields, they will have to sign him to a sizable extension, and they'll still have a subpar QB at the helm of a team with growing talent. That likely gets Eberflus canned.
If they dump Fields and draft say, Caleb Williams, they get a first year QB out there who will likely make a lot of mistakes and probably get Eberflus canned, meaning they bring in a new coach and system for a young QB.

Either way it's a bit of a mess. Ideally you want to line up a new young QB with a coach who has some job stability.
