Like the rest of the defense, the Cardinals linebackers got off to a poor start in the first seven games of the season, but they were a totally different unit in the final nine.
In only his second season in the league, Daryl Washington became one of the main leaders of the defense. His 106 tackles led the entire team and he also had a pair of interceptions. At 25 years old, D-Wash is on the verge of becoming one of the best young linebackers in the league.
Alongside Washington will be Paris Lenon, who will return for his third straight season unless something strange happens during the offseason. The veteran was second in the team in tackles behind Washington. Behind both players will be Stewart Bradley, who was signed to a big contract last summer, but saw little action on defense and spent most of his time on special teams.
If the Cardinals decide to cut him, they could be in store for a younger option at the inside 'backer spot to go alongside Washington. Many draft boards have Arizona taking Luke Kuechly out of Boston College at No. 13. If he is available, he might be too hard to pass up even if the Cards decide to hold onto Bradley.
Whisenhunt has proven that he is willing to take the best available talent on the board the past couple of drafts.
Arizona could be looking to add another body on the outside as well. Sam Acho is all but locked in for one of the spots. Playing very little in the first six weeks of the season, the former Longhorn had seven sacks in the final 11 weeks.
There are still questions on the other side though. O'Brien Schofield is a youngster that the staff loves, but they might not be quite ready to give him the starter's job. Longtime Cardinal Clark Haggans is a free agent. He played well in the final few weeks, but at 35, the organization might be looking for a younger option either through the draft or free agency.
