Is DA trying to recreate the 2009 defense?

Uhh no. For you to do that it would require 1 leaving your CBs on a island in press coverage . With a FS center fielder with range instinct and hands of a God.
A punishing SS whose used in the box and put at the line of scrimmage , good instincts

Crazy thing is we have the players that fit these roles it’s simply DA isn’t putting them in the position to succeed

We have the CBs but DA wants to play them 5-10 yards off

We have the FS but he can’t tackle and isn’t put in the center field often

M.Jenkins is asked to cover 6’7 players with no help , and he isn’t allowed to jam them at the line I’m guessing not is any other player

Don’t ever compare DA to Gregg Williams not that Gregg was perfect but he trusted his players to get the job done.
