The Cardinals announced that coach Ken Whisenhunt and general manager Rod Graves signed extensions Thursday to remain with the team through 2013. Whisenhunt's contract, which also has a team option for 2014, puts him among the five highest-paid coaches in the NFL, a league source told NFL Network insider Jason La Canfora, and averages over $5 million per season. Whisenhunt and Graves have led the franchise to new heights, reaching Super Bowl XLIII and winning a playoff game in 2009 before falling to the eventual champion Saints. "The outstanding work of these two individuals has been a vital part of the organization's accomplishments," Cardinals president Michael Bidwill said in a statement released by the team. "Rod and his staff have done an exceptional job in evaluating talent and building a roster that will produce sustained success. Obviously Ken Whisenhunt's achievements as a head coach speak for themselves.
