Defensive coordinator: A defensive coordinator is a member of the coaching staff of a gridiron football team who is in charge of the defense.  Generally, along with the offensive coordinator, he represents the second level of command structure after the head coach.  The defensive coordinator is generally in charge of managing all defensive players and assistant coaches, of developing a general defensive game plan, and of calling the plays for the defense during the game.  At higher levels of football (college and professional), the defensive coordinator typically has a number of assistant coaches working under him who are responsible for the various defensive positions on the team (such as defensive line, linebackers, or defensive backs).  You can look to the links under references for some of the best defensive coordinators in history according to Bleacher report.  John Chavis (American football) and Jeremy Pruitt are among two of the great college defensive coordinators in recent history.  There are Also many NFL greats that can be found in the references.  People like Wade Phillips and Vic Fangio are among the NFL greats at defensive coordinator.  Determining how good a defensive coordinator is has to do with a number of things such as defensive statistics, the type of attitude their players took to the field and also what other coaches and players had to say about them.
