The Cardinals acquired additional secondary depth Wednesday by trading fullback and special-teams captain Anthony Sherman to Kansas City for cornerback Javier Arenas.
Arenas (5-9, 197) was a second-round draft pick out of alabama in 2010 who spent three seasons with the Chiefs. He has 12 career starts — nine of those in 2012 — and two career interceptions. He saw considerable action as a return specialist for the Chiefs, averaging 9.8 yards on 153 career punt returns and 21.0 yards on 50 kickoff returns. He was third in the NFL in punt return average in 2011 (12.8 yards per return).
Arenas is the third new cornerback acquired by the Cardinals this off-season, along with Jerraud Powers and Antoine Cason. They join three holdovers: starter Patrick Peterson and second-year players Jamell Fleming and Justin Bethel.
Sherman was deemed expendable because new head coach Bruce Arians’ offense has no use for a fullback.
