Currently, there are 31 running backs in NFL history who have at least 7,000 rushing yards and have rushed for at least 70 yards per game. Among that group, Peterson and Charles are two of just six players to spend their entire careers with one team — and that is likely going to change. Can you guess the first 4? Take a second.
Those thresholds aren’t insanely high. To put some scope on those thresholds, drop them to 6500/65 and you bring in Robert Smith of the Vikings, and a pair of Giants in Tiki Barber and Rodney Hampton.
For comparison’s sake, there are 30 wide receivers who have at least 6,000 receiving yards and a career average of at least 60 receiving yards per game. Even excluding the six receivers who are still active, Don Hutson, Charley Hennigan, Steve Largent, Sterling Sharpe, Michael Irvin, Marvin Harrison, Reggie Wayne, Marques Colston, and Calvin Johnson all retired and played for just one team; they represent nearly half — 9 of 19 — of the retired players in the 6000/60 club.
I don’t have much to add to that, other than I find it kind of interesting.
