He is expected to compete against Shareece Wright and Will Davis for a starting job opposite Jimmy Smith. Analysis: Powers started 13 games last season for Arizona, finishing with 52 tackles, an interception and a sack. The 28-year-old Powers played the first four years of his career with Indianapolis and the last three with the Cardinals. He has started 82 of 87 games. Signing Powers as a free agent Friday won't cost the Ravens a compensatory because the deal occurred after May 12.
