In Texas there are only three answers
Adrian Peterson (Palestine, TX)
Earl Campbell (Tyler, TX)
Cedric Benson (Midland, TX)
The first two are self-explanatory - East Texas grown men at 16 years old.
Cedric was an absolute tank in high school. Fully developed just like the other two but maybe lacked maturity/focus. But some view him as the best running in TXHSFB history.
