Just read this and wanted to post it cuz I thought it was pretty cool. The only complaint I have is that I believe Sanders and Payton should be flip-flopped. Barry was definitely the most electrifying, but any RB who had to be taken out around the goal line, put up terrible postseason numbers and quit on his team should NOT be ahead of Sweetness, who was quite the contrary in all of those categories...

Don Shula, Marv Levy, Emmitt Thomas, Jack Bushofsky, Dan Reeves, Jerry
Richardson, Robert Smith and Floyd Reese helped ESPN evaluate the
best running backs in NFL history. ESPN.com weighed their
contributions, balancing rankings with anecdotal evidence and
statistics to create the following list:
1. JIM BROWN
Career: Upon retiring before '66 season, the Browns' RB was
all-time leader in rushing yards (12,312), all-purpose yards (15,549)
and touchdowns (126).
Quick quote: "Incredible combination of speed and power. As a
defensive back, I'm happy he retired just as I came into the league,
because my career might have been a lot shorter if I had to tackle
him.'' -- Thomas
2. BARRY SANDERS
Career: Sudden retirement in '99 came with the Lions' RB
trailing only Walter Payton on the all-time rushing list. Ran for more
than 1,500 yards in a season five times.
Quick quote: "He's the only guy I've ever seen who could hurt
defenders without touching them. He'd have them twisting their ankles
and running into each other.'' -- Reese
3. WALTER PAYTON
Career: Played on mediocre Bears teams until late in career but retired as leading rusher (16,726) in history.
Quick quote: "The most complete back ever."' -- Shula
4. EMMITT SMITH
Career: Smith, who played 13 seasons for Dallas and two for
Arizona, took over as all-time rushing leader in '02. His 164 rushing
touchdowns are the most in history.
Quick quote: "Phenomenal and extremely tough player. Incredible balance and leverage.'' -- Reeves
5. GALE SAYERS
Career: Knee problems forced him to retire in '71 after seven
seasons with the Bears. At 33, he was the youngest person selected to
the Pro Football Hall of Fame.
Quick quote: "I used to watch him and say, 'How can anybody be that good?'" -- Levy
6. LADAINIAN TOMLINSON
Career: The Chargers' RB has at least 1,200 rushing yards and 50 receptions in each of his first seven seasons.
Quick quote: "He brings as much versatility as any running back ever has.'' -- Smith
7. MARSHALL FAULK
Career: Began career with Indianapolis in '94 but was traded to
St. Louis in '99 and became cornerstone of "Greatest Show on Turf."
First running back in history to lead his team in receptions in five
different seasons.
Quick quote: "Could have been an All-Pro as a wide receiver.'' -- Bushofsky
8. O.J. SIMPSON
Career: The Bills' great became the first player in NFL history to rush for 2,000 yards in a season when he gained 2,003 in '73.
Quick quote: "He had it all. He had the same type balance as Jim Brown, and he could just keep going and going.'' -- Reeves
9. LENNY MOORE
Credentials: One of Johnny Unitas' key weapons for the Colts, he
scored a touchdown in 18 straight regular-season appearances between
'63 and '65.
Quick quote: "He may be underappreciated, but he was very
similar to what Marshall Faulk has been more recently.'' -- Richardson,
who was Moore's teammate for two years in Baltimore.
10. ERIC DICKERSON
Credentials: Reached 10,000 rushing yards in 91 games (the
fastest pace in history) and rushed for 2,105 yards in '84. Played for
Rams, Colts, Falcons and Raiders.
Quick quote: "He didn't look fast, but he was so long-legged that he could go the distance.'' -- Reeves
