Question

With Washington having released Derrius Guice, the chances of Adrian Peterson being its starting running back have increased. At 35, he potentially could become the league’s oldest-ever 1,000-yard runner. Currently, there are only two 35-year-olds who have gone over 1,000. Who are these backs? They did it 20 years apart. (Both of these backs were 35, but both were over 4 months younger than Peterson.)

Answer

John Henry Johnson (Steelers, 1964)
John Riggins (Washington, 1984)
