NBA Gets an A+ For Diversity From An Institute That Gets An F for Diversity of Its Top Management

The chart above is based on data from the "The 2010 Racial and Gender Report Card: National Basketball Association," released today by the University of Central Florida's Institute for Diversity and Ethics in Sports.  The overall grade this year for the NBA was an A for "Race" (same as last year), with a grade of A+ for the sub-category "NBA Players." 

According to a news article titled "NBA gets an 'A' for diversity" from ESPN, "The NBA still leads the way in sports diversity."

Compared to the overall population, whites, Hispanics and Asians are significantly underrepresented in the NBA by margins that aren't even close, e.g. whites are 75% of the population but only 18% of the NBA players, and the same huge disparities exist for Hispanics and Asians.  For all three groups, their numbers in the NBA would have to increase between 4-5 times for their representation in the NBA to be proportional to the general population. On the other hand, blacks are overrepresented by more than a factor of six compared to their share of the general population.  

Q: Just wondering, if this outcome gets a score of A+ for diversity, what would a score of F would look like?? 

In case you're wondering who's in charge of the Institute of Diversity and Ethics at UCF, it's run by two white guys who are listed as the organization's top administrators (see photo below).  What grade do they give their own organization, especially for the category of "Top Management" (one of the categories they use for the NBA)?  Would that be an F for being 100% white male?
