You might argue that the Falcons entered a new era when they fired all three of their coordinators following the 2018 season. You might more credibly argue that they entered a new era when they fired Thomas Dimitroff and Dan Quinn, replacing the duo with Terry Fontenot and Arthur Smith as general manager and head coach. Hell, you could say that Matt Ryan being shipped out to Indianapolis signaled the beginning of that new era. It has been an era of new eras in Atlanta.
I’d take a slightly different tack and argue that the past five seasons have all been part and parcel of the same era, despite the shifting personnel and dramatic moves.
