Jim Brown of the Cleveland Browns is widely respected as the greatest football player of all time, and the model running back who did everything well. Younger fans have probably heard their parents and grandparents describe him.
He was, big, fast, tough, smart, and unbelievably quick. He could go around you, but mainly he ran right over you. He was also a punishing blocker for halfbacks Bobby Washington and Ernie Green. Brown could also pick up the blitz and pick up passes. He completely mastered virtually every aspect of being a running back in the NFL.
