That is where frazier came from also. They were all apart of Johnson's defenses in Philly together. Frazier was older and higher on the staff than mcdermott was. Plus frazier played (with ron rivera) on the bears teams in the 80s with Ditka and Ryan.
The bottom line is the chef who is stirring the spoon may be different but the ingredients and the recipe is going to be the same because Mcdermott and frazier are all basically using the same recipe that goes back to those jim johnson staffs in philly with Rivera, spagnuolo etc.
IMO, it will be different when we see it be different. They may pick their spots to be more aggressive but I do not think there is this big huge change coming.
