Jim Brown is what every running back in the past 50 years has viewed as the bar for success. He only played nine seasons during his football career, opting to do other things early in life, but those nine seasons were ones unlike anything we've ever seen. Brown led the league in rushing eight of those seasons, had a record holding 104.3 rushing yards per game average, led his Cleveland Browns to a championship, and let the football world know that running backs could be dominant. The dude wasn't afraid of anything either, Brown never shied away from contact on the field but still never missed a game. He also had no problem voicing his opinion to the media and used his celebrity to fight for causes he believed in. There is no Barry Sanders, Adrian Peterson, or Walter Payton without Jim Brown. He is the greatest running back of all time.
