The Raiders have signed veteran cornerback Ricky Manning Jr. in a move to add depth to their secondary. Manning spent last season with the Rams, and the cornerback has made trips to the Super Bowl with the Bears and Panthers in his career. "He's more of a physical corner than a speed guy, so that might be a little different from what we had in the past," Nnamdi Asomugha said, according to the Oakland Tribune. "But he'll help because he's done it before. And you know about the games that he's played, his playoff work and all that stuff, so he can play."
