Edgerrin James told ESPN's Bob Holtzman that he won't return to the Arizona Cardinals next season even though he has a year remaining on his contract. "I can't go through this again," James told ESPN. "I didn't come here to block. I'm not an offensive lineman." James, who re-emerged as the Cardinals' feature back in the regular-season finale after weeks of pass-blocking and barely touching the football, told reporters Thursday that his last game of the season will probably be his last in Arizona. "I think the feeling is mutual," he said, laughing. "It's not something I'm going to contest."
