There are good reasons that Florida, California, Texas, and Georgia produce so many high quality athletes. Population, climate, school emphasis on sports, ample parks/ballfields/courts, and strong competition.
Which is why we have to recruit strongly outside the borders. Take the best in-state, go get the best you can everywhere else. If 40 players on the roster are from TN, they have done their jobs now that Nashville and Memphis areas have grown so large in population. But forget the roster going much past 40 is you want the program to be elite.
