Actually, I think there are only about 3 million people in the area that the TP is talking about (Lafayette, Baton Rouge, New Orleans). That's less than 1% of the population of the country -- with 6% of the Super Bowl rosters. I think that's may be more than 2 s.d. above the mean of the normal distribution and thus significant under the t tests, though I'm not sure what the appropriate n should be here.
That is, I think we can reject the null hypothesis that SE LA doesn't produce an unusally large crop of football players.
