The Arizona Cardinals traded down seven spots in the NFL draft to select safety Deone Bucannon of Washington State with the 27th pick overall.
The Cardinals dealt their No. 20 pick to New Orleans, getting the Saints' first-round pick and their third-round choice, No. 91 overall.
The selection of the 6-foot-1, 211-pound Bucannon adds a needed component to a defense that was ranked sixth in the NFL last season but had difficulty defending the league's big tight ends. He joins second-year safety Tyrann Mathieu, who is coming back from knee surgery.
Bucannon had 15 interceptions as a four-year starter at Washington State.
Arizona had only six picks before the draft-night trade, having sent its seventh-round selection to Oakland as part of the Carson Palmer trade.
