Today, I take that a step further. Essentially, I've taken that data and run a few correlations. On one side, I have the relative ability of the state (controlling for the size of the relevant population-that is, college-aged men) to produce players or statistics. On the other hand, I have the percent of the state that is Black. A positive correlation means that as the relative size of the Black population increases, that state produces more players in that position or more of that statistic. Again I will emphasize that this is a simple correlation and, as such, hints at a pattern but is far from definitive evidence of anything.
Looking at the results, states with relatively large Black populations are exceptionally good at producing DBs, RBs, and WRs. They also produce an exceptional number of rushing and receiving yards. In all cases, the correlation is positive and large.
