The New York Giants hired James Bettcher as their new defensive coordinator in January. Bettcher had previously been the defensive coordinator of the Arizona Cardinals, where he employed a 3-4 defensive scheme.
The team is in an interesting position, as they have only $14 million in cap space according to over the cap. This obviously means that they will have to be creative in how they shape their team.
The Giants have the talent on the roster to make the shift to a 3-4 defensive scheme without any major shifts in personnel.
