The clear trend today with RBs is to limit them to around 20 carries per game, with a few exceptions. With 20 touches and 7 ypg, well, you do the math, a great game but not beyond the pale.
The "Pale" interesting, perhaps, is the area around Dublin, Ireland.
Is it more impressive to have 20 carries and 7 ypc or 35 carries and 4 ypc? It depends.
What Sanders did in the League is tough to ignore. He did not exactly have an all Pro line up there.
