Are the salaries the mean or the median? A few highly paid skill position players (and left tackles, if you believe The Blind Side) could tip those stats if it's mean.

Has to be the median or they excluded NFL salaries.  Otherwise the UT, UF, OSU ROI would not be so much lower than the overall ROI.  Unless the non-NFL football players from these schools are all unemployed?

I have my doubts about this data.  How on earth did they did total lifetime earnings of football players, let alone broken out by race?
