Last year, DeMarco Murray led the NFL with 1,845 rushing yards. The 32nd-ranked rusher last season rushed for 570 yards, which means Murray rushed for 1,275 yards more than the Nth-ranked rusher, with N representing the number of teams in the NFL. That’s obviously excellent, although not quite the best of all time.
That honor, as regular readers could have guessed, belongs to O.J. Simpson. In 1973, Simpson rushed for an incredible 2,003 yards, while the 26th-ranked rusher in the 26-team NFL rushed for 655 yards. As a result, Simpson is credited with 1,348 yards over the Nth-ranked rusher. Then again, remember that this was a 14-game NFL season; we need to pro-rate that number to 16 games to make for a fairer comparison. That brings Simpson’s season up to +1,540, slightly edging out Adrian Peterson‘s 2012 season (2,097, 564, +1533).
What if we use that methodology for every player during every season of his career? That, to me, is an improvement on just a list of the career rushing leaders, since we don’t give players any benefit for junk seasons. That may be the only thing this list is an improvement on — after all, it is still based on only one statistic — but hey, it’s Friday. Below are the career grades for the top 150 running backs (note that by default, the table only displays the top 25). I have also listed for each back his career rushing yards and his rank in that category. [click to continue…]
