Nnamdi Asomugha has signed with the San Francisco 49ers after two disastrous season with the Philadelphia Eagles.

"I don't know that there's been a season where I didn't go in feeling like I had something to prove," Asomugha said. "I've had a chip on my shoulder every year that I've played.

"I think, obviously, it's bigger this year because of the adversity I went through in Philadelphia. But it's always been a part of my game, coming in and showing what I can do and now being able to be here and start fresh with that, it's a great opportunity for that."

Asomugha was once mentioned in the conversation with Darrelle Revis as the best cornerback in the NFL.
