ORLANDO, Fla. --- Two days after the election of the country's first black president, a study shows the number of African-American coaches in major college football is the lowest in 15 years.

With the recent dismissals of Ty Willingham at Washington and Ron Prince at Kansas State, the number of black head coaches in the 119-school NCAA Football Bowl Subdivision was reduced to four.

In 1997, there were eight black head coaches, the most in history. In 1993, there were only three.

Fifty-five percent of all student athletes are minorities.

The report by The Institute for Diversity and Ethics in Sport at the University of Central Florida polled every major college on the ethnicity of its coaches, athletic directors, presidents, faculty, student athletes and NCAA faculty representatives.

"While the percentages are slightly better, the general picture is still one of white men running college sport," said Richard Lapchick, the report's co-author.

The report also looked at university leadership, including presidents and athletic directors. Ninety-one percent are white. (Georgia's athletic director, Damon Evans, is black.) Minority representation in all positions increased less than 1 percent last year.

Charlotte Westerhaus, NCAA vice president for diversity and inclusion, said she was disappointed in the figures, particularly considering the election.

Lapchick has asked the NCAA to adopt a rule to mandate that minorities be interviewed for head coaching jobs. Calling it the "Eddie Robinson Rule," in reference to the record-setting Grambling coach, Lapchick said it would be a college version of the NFL's Rooney Rule. The NFL sanctions teams that do not interview a minority candidate.

Since 1996, 12 black head coaches have been hired for 199 jobs. The four set to finish the season are Miami's Randy Shannon, Mississippi State's Sylvester Croom, Buffalo's Turner Gill and Houston's Kevin Sumlin.
