Sanders should get no sympathy from Steven Jackson.
Weighted Winning Percentages
Sanders' Lions reached the playoffs in five of his 10 seasons, posting between nine and 12 victories each time. They never won fewer than five games in a season.
Jackson's St. Louis Rams have never won more than eight games in a season. His teams have fared so poorly, in fact, that Jackson ranks last on a list of 87 top running backs ranked by team winning percentages. Chase Stuart, best known for his work at Pro Football Reference, published the list at his new site, Football Perspective.
Sanders ranked 68th.
The list considers runners with at least 5,000 yards rushing and 7,500 yards from scrimmage. The winning percentages were weighted to favor runners' most productive seasons.
"For example, if a player gained 10 percent of his [career] yards from scrimmage in 1999 and the team went 15-1 that season, then 10 percent of the running back’s weighted winning percentage would be 0.9375," Stuart explains. "This is designed to align a running back's best seasons with his team's records in those years.
"For example, Emmitt Smith played two of his 15 seasons with the Cardinals. But since he gained only 6.5 percent of his career yards from scrimmage in Arizona, the Cardinals' records those years count for only 6.5 percent -- and not 13.3 percent -- of his career weighted winning percentage."
The methodology is a little confusing at first glance, but the results make sense.
Jackson has played eight seasons, fighting off injuries and the malaise perpetual losing cultivates. He has played eight seasons without flinching. His bruising style naturally raises questions about how long Jackson might hold up physically. But it's also fair to wonder how much losing such a passionate player can withstand before deciding he's had enough.
The backs listed atop Stuart's list faced no such issues.
Former Los Angeles Rams great Lawrence McCutcheon, named to five consecutive Pro Bowls under coach Chuck Knox, tops the list with a .741 weighted winning percentage. Roger Craig, named to four Pro Bowls with San Francisco, ranks third at .723.
NFC West alums Garrison Hearst (20th), Shaun Alexander (22th), Ricky Watters (23rd) and Wendell Tyler (24th) are all at .585 and higher. But four of the six players at the bottom of the list also spent some of their careers with franchises currently aligned in the division. That includes Hall of Famers Ollie Matson and O.J. Simpson.
