He notices it nowadays as a veteran receiver for the Arizona Rattlers of the Arena Football League -- he's regarded as perhaps the best receiver in the 29-year history of the league.
He notices those smiles when he sees photos of himself as a standout at Nebraska in 2006 and 2007. Back then, however, he smiled through pain. Pain so debilitating that he spiraled into a depression, although he could usually function well on the field.
