Whisenhunt has Cardinals adding 3-4 to defense

First-year coach Ken Whisenhunt is an offensive coordinator by trade, of course, but the most notable differences in the Arizona Cardinals when they convene for their initial three-day minicamp this weekend might actually be on defense.

It's the job of every head coach to impose his fingerprint on every facet of a team, not just his primary area of expertise, and Whisenhunt is aiming to do just that with the Cardinals. And quickly.

Whisenhunt has considerable exposure to the 3-4 defense from his six seasons working with Dick LeBeau in Pittsburgh. And he has now asked holdover defensive coordinator Clancy Pendergast, an innovative guy whose personal preference has been the 4-3 front, to incorporate some 3-4 elements into what the Cardinals do in 2007.
