When the incident occurred, Smith said he did consider the ramifications it could have on his career. "You definitely think about what happened, how you want to be perceived and how you want your career to go," Smith said, adding that he felt he let his fans down.

Smith is projected to start for the first time this season, having served as a pass-rush specialist last season while Parys Haralson and Ahmad Brooks started all 16 games at outside linebacker.
