My definition of a natural running back, the first person that comes to mind is Edgerrin James and Warrick Dunn. The natural ability to anticipate blocks, knows when to be patient or hit the hole hard, has good speed, good agility, runs with a low center of gravity, good out the backfield in the pass game, and a good blocker. Whereas some folk might prefer Eric ****erson or OJ Simpson, others may prefer Barry Sanders or Emmit Smith. All were great backs, but its all about preference and productivity. Lingard was definitely more productive out of high school.
