Gurley spent a whole year being "off"

And he recovered to be arguably the best RB in the NFL. He's dinged, it happens. He lost some concentration on Sunday, it happens to the best. But many players come back again and again from far worse, Adrian Peterson is an example of that.

If this continues into next season, I would be concerned but this is money and fame ball now and his legacy remains unaffected. Eventually his body will break down as age affects us all but I do not see that yet.
