The Cardinals? first step into free agency will apparently have an Edge to it. Despite numerous denials from the Cards that they would chase a big-name running back, multiple NFL sources confirmed Colts running back Edgerrin James ? arguably the biggest name on the free agent market ? is expected to visit Arizona today. Free agency began Friday night at 10:01 p.m. Attempts to reach vice president of football operations Rod Graves late Friday night were unsuccessful. James? agent, Drew Rosenhaus, did not return a phone message.
