I also love McDermott's "Be One eleventh" of the defense concept as well. He has those guys playing as a true Team, and one that looks to be well coached. McD focused on bringing in coaches who were good teachers and IMO it's showing... in everything from fundamentals to scheme & execution to discipline (etc).
I agree mostly except OL. Maybe the players we have do not fit the scheme exactly but then you need to adapt until you do. Glenn being hurt is not an excuse.
