Arguably the top cover corner in the NFL today, Nnamdi Asomugha has been a rising star since being drafted out of the University of California at Berkeley, in the first round in 2003 by the Oakland Raiders.

A four-time NFL All-Pro and one of the true "shut down" corners in the game, Nnamdi's contributions may be even greater off the field. With a long and impressive list of accolades for his tireless philanthropic efforts, Nnamdi was awarded the NFL's 44th annual NFL Man of the Year award from the NFL Players Association in 2010.

Now here's your chance to have a true collectible from this outstanding NFL player.  An Oakland Raiders Football Autographed by Nnamdi Asomugha #21.
