It looks to me like the methodology here was to take the expected 30-year return for all graduates of a particular college, and then to apply that number to that school's graduation rates for football players, including football players of different races. (Salary info for all graduates would likely yield a much tighter bunching of the median and mean numbers than salary info for football players would.)

I'm sure there's no publicly available data on how much money football players from different schools can be expected to make over 30 years. But even if there were, and means were used instead of medians, I'm not sure the football factories would fare all that well in this comparison. Keep in mind that NFL careers tend to be quite short.
