I may be using the wrong terms. I am talking about defending deep but still having a credible threat of attack that stops opposition teams from building at their leisure and forces them to keep players back to defend against that threat.Deep defensive line is safer than a high line.
Edit: Duke stays high but he is not a credible attack from halfway with his lack of pace and guile.
When we stop attacking to put everyone deep and invite the best our opponents can bring down on us.
