You have not seen this episode. This is first time you have seen a whole defensive staff that has not worked for the jones in a meaningful capacity.
These are not the types of coaches the Jones boys like. They want older guys they are comfortable with, have worked with and know they can manipulate.
Now Last Year with Eberflus and the year before with Zimmer I would agree with you. This is not that staff.
With that said, still does not mean it will work out. It might go to hell in a handbasket as they are all so young and most do not have any hc or DC type exp. And of course if they do not take FA seriously and do not hit on the draft picks, it will not matter anyway.
