Jay Ajayi became the season’s first 200-yard rusher on Sunday, going for 204 yards against the Steelers. And following recent form, he did so as a relatively unheralded back – a guy who’s probably bounced off and on some waiver wires.

This isn’t new.

In the past 10 years, there have been 41 200-yard rushers. Well over half of those rushers (26) are players who didn’t rank in the top 20 at their position the previous year. That’s using standard scoring.

Only 7 of the 41 are backs who were top-10 guys the previous year.

Running back, most certainly, is a position of change.

On the list presented here, the seven top-10 backs (from the previous year) are in bold. The 26 who came from outside the top 20 have a black ball.
