It's been that way for a while now, but the media is just catching up because standard positions and 4-3 vs 3-4 defenses really don't exist in todays game. Aside from Corners, everything has basically turned into some degree of a hybrid position.
By today's standards everyone pretty much falls into either an Edge, IDL, Off ball LB, CB, FS, or hybrid Safety/LB. It's all about position flex based on the matchups week to week.
Our traditional understanding of a defensive depth chart is almost dead.
