What former Vols have had the best NFL careers? Obviously Witten, a first ballot guy. Chad Clifton played for years. Dale Carter had a great career. Pickens was one of the best wideouts in the league, despite wasting his career with Cincinnati. Alvin Harper was not the same w/o the play maker on the other side but he had a solid NFL resume. Jamal Lewis damn near broke the single season rushing record.
