One of the greatest accomplishments of Campbell's career is one that doesn't get a lot of attention among football fans. He was unique in that he excelled at all levels while playing in Texas -- he was one of the top players in the nation at Tyler High School, won the Heisman Trophy at the University of Texas, and was a perennial all-pro early in his career with the Houston Oilers.
In 1981 the Texas legislature honored Campbell by naming him an Official State Hero of Texas -- an award that has been given to only three other figures in Texas history (Davy Crockett, Stephen F. Austin, and Sam Houston).
