Reflecting back over the last three coaches to have stayed a full season, Dan Quinn, Mike Smith, and Jim Mora Jr, the Atlanta Falcons defense has been atrocious under the three of them. What makes this confounding is that all three of them are defensive coaches.
When you take out the 2007 season under Bobby Petrino and look at the other 15 NFL season under those three coaches, you have to shake your head and wonder how the Falcons defense has been as bad as it has.
People love to talk about total defense as a way to measure success but in reality, you should always look at scoring defense. How many points is your defense actually giving up is a much more important stat given teams cant beat you with 400 yards and zero points on the board.
