Inducted in the 2006 Colorado Springs Hall of Fame, and the Colorado High School Hall of Fame in 1993, Darryl Clack began his college football career at Arizona State University in the 1982 season, becoming the first freshman to lead the Sun Devils in rushing in 30 years. 


His freshman season culminated in the Devils' victory over Oklahoma in the Fiesta Bowl, with Clack scoring a third-quarter touchdown. Even as a freshman, his popularity galvanized Arizona State fans, to the extent that metal noisemakers known as "Darryl Clackers," were sold by stadium vendors.


He continued to excel at Arizona State, leading the Pacific-10 Conference with an average of 93.2 yards rushing per game in his sophomore year and rushing for over 1,000 yards, earning MVP honors, in his junior year. His promising collegiate career was cut short when a broken leg sidelined him for seven games as a senior.


The Dallas Cowboys drafted him in the second round of the 1986 NFL Draft, to be the backup and possible successor to Tony Dorsett. With Herschel Walker's arrival to the team,  the talent level at running back relegated him to returning kickoffs. He was the NFC's third-leading kickoff returner in 1988.


In 1990 he signed with the Cleveland Browns.  In 1991 he was signed by the Toronto Argonauts of the Canadian Football League, where he played in the Grey Cup championship game.


In 1992, he signed with the Orlando Thunder of the World League of American Football. He became the team's starter at running back and received All-World League honors at the end of the season. 


After football, he buckled down and returned to school earning a B.A. in Kinesiology and Sports Studies from the University of Texas at El Paso, and an M.A. in Organizational Management from the University of Phoenix.  He was in his first year of working towards a Ph.D. when he fell ill to Thrombotic thrombocytopenic purpura (TTP), a rare blood disorder that he's currently being treated for. 


Although he is no longer playing ball, he keeps his hand in the game as President and co-founder of SportMetric, along with co-founders Josh Jakubczak and Darius Perry, a company emphasizing education, community involvement, and athletics for the youth.
