In every press conference and interview, MCDC always talks about “limiting the explosives.” If you were drawing up a defensive scheme where the number 1 priority was limiting explosive plays, you’d have the Lions:
Cornerbacks play soft off coverage
Safetys play deep
Linebackers never blitz, and always have eyes on the quarterback in a zone scheme. On running plays they play sideline-to-sideline, but never downhill.
Defensive line plays a 2 gap mush-rush scheme, where keeping contain is more important than getting sacks or tackles for losses.
What the coach says to the press is not going to be 1:1 with what he thinks or what he is actually doing behind the scenes.
