Free agent CB Nnamdi Asomugha has decided to retire. He was released in November. Asomugha is only 32, but simply has nothing left. jm91rs says: Dec 26, 2013 10:11 PM Pro Football Talk Most overrated db ever. The tape never showed that he was a shut down corner. Most of the experts knew that, yet fans continued to act like he was. What happened in Philly was very predictable, no way you can blame how he was used, unless you mean teams actually realized he could be beaten pretty easily.
