Quote:  Probably the greatest differences between Jim Schwartz and the coaches you mentioned is Schwartz seems to prefer using Zone Coverages more often and relying on the blitz less.   One of the major criticisms with Schwartz in Detroit was he didn't blitz often enough,  despite having a Defensive Coordinator in Gunther Cunningham who had a major history of liking to turn things loose  ( blitz  ).

 

  In addition to the coaching tree you mentioned,  Schwartz is also from the Bill Belichick tree from his days with the Browns.
