Brian Kelly is a football coach. Some are smarter than others. Somebody asked him a question and he rambles on, throwing random crap in the air. This is not where I would look for deep meaning.How else would you interpret "There’s not a lot of other things that take them away from field sports"? There's still electricity and playstations and iphones and movie theaters. The only thing that prevents those things from being available would be if you're poor.
Bottom line: he said it's better recruiting football talent in the south than elsewhere. He's right.
