I used to post the chart on Canestime that showed where NFL players come from and south Florida owned by far.
There's no doubt South Florida is the best region in the nation. Simple reason for that: just look at the Pop Warner system.
South Florida has the best youth football in the world. The kids start early, and they have incredible pressure put on them early by the community and their families. South Florida moms are tougher on their kids than Bear Bryant.
That breeds the mental toughness and confidence that allows them to contribute early in college and in the pros.
