Former Chargers CB Antoine Cason is visiting Arizona. A graduate of University of Arizona, Cason had a stellar career in Tuscon, which ended with him being awarded the Jim Thorpe awards as a senior. In San Diego, Cason started 45 games over 3 seasons, recording 12 interceptions. Last season, he made 73 tackles, along with 2 interceptions. The Cardinals desperately need CB depth, after releasing William Gay, and losing Toler to the Colts. Cason, who's only 26, would be a solid pickup, and along with Peterson, would create a formidable secondary.
