Is anyone close to Emmitt Smith's rushing record?
Smith's 18,355 rushing yards is nearly 2,000 more than second-place Walter Payton's 16,726.
The next five names on the career list are all retired: Barry Sanders, Curtis Martin, Jerome Bettis, Eric Dickerson and Tony Dorsett.
The top active rusher is LaDainian Tomlinson, whose 12,490 yards are in eighth place. He will play his first season with the Jets after spending the first nine years of his career in San Diego.
Edgerrin James, who played for Seattle in 2009, has 12,246 yards _ good for 11th place. Unfortunately for James, who hasn't announced his retirement, he doesn't yet have a team for this season.
Other top running backs who were active in 2009 include: Fred Taylor (15th on the career list), Jamal Lewis (21st), Clinton Portis (26th), Thomas Jones (29th), Ahman Green (30th) and Ricky Williams (32nd).
Taylor is still recovering from an ankle injury that limited him to six games last season with the Patriots.
With Lewis retiring and Green joining the United Football League's Omaha Nighthawks, only Portis, Jones and Williams seem likely to add significantly to their totals.
Adrian Peterson, whose 4,484 yards rank him 136th, is the top back 25 years old or younger.
Fellow Hall of Fame inductee Jerry Rice has an even more definitive stranglehold on many statistical categories, including career receiving yards.
His 22,895 is more than 7,000 better than second-place Isaac Bruce's 15,208.
New Cincinnati Bengal Terrell Owens is third with 14,951, followed by former Raider Tim Brown and Marvin Harrison, who last played for the Colts in 2008.
Randy Moss is sixth with 14,465 yards. Former Chief Tony Gonzalez enters 2010 in 19th place with 11,807 yards.
