That's how head coach Mike McCarthy assessed the initial fallout of the massive shakeup he initiated with the team's defense in the wake of the struggling unit's role in the 6-10 record last season.

"Change is part of our business. It comes in different forms," McCarthy said. "But, we're excited about the new direction we're going with our defense."

Besides removing all but two defensive coaches from his staff, McCarthy tore apart the foundation of the defense itself. The hiring of onetime NFL head coach and longtime defensive guru Dom Capers as coordinator, along with the additions of several big-name position coaches, brought about a radical change from a 4-3 scheme to a 3-4.

Personnel will be affected at all positions on the defense, most notably Aaron Kampman. McCarthy said the Pro Bowl end would be moving to outside linebacker.

McCarthy doesn't feel the switch is too significant for Kampman, who is entering his eighth year in the league and hasn't played linebacker since his sophomore year of college at Iowa.

"Aaron Kampman knows how to rush the passer, and the first responsibility for the outside-linebacker position in the base personnel is to rush the passer," McCarthy said. "Aaron Kampman is going to be an excellent fit for what we're going to try to do as we move forward with this new scheme."

While Kampman will be making the position adjustment in the team's offseason program, the secondary will have to get acclimated to coverage responsibilities in the 3-4 system that could compromise the vaunted bump-and-run traits of veteran Pro Bowl cornerbacks Charles Woodson and Al Harris.

"They're going to have to be ready to embrace change," said new safeties coach Darren Perry, a 3-4 proponent. "Change can be a little uncomfortable because we're creatures of habit and people don't like change.

"The system is proven, it works, and it can be a great system if everybody gets on the same page, if you have a bunch of unselfish guys that are willing to just do their part."
