The Green Bay Packers defense is now ranked #1 in the NFL.  Dom Capers and the coaching staff have taken the woeful defense from a year ago a long way.  The scheme change from a 4-3 to a 3-4 alignment washeavily criticized earlier this season when fans were outraged at the 'misuse' of key players like OLB Aaron Kampman and CB Al Harris.  With both of these players lost for the season to ACL injuries, the Packers look to maintain their ranking atop the NFL as they ready for tough match-ups against two premier defenses in Pittsburgh and Baltimore.
