Adrian Peterson has earned his status as one of the greatest running backs of all time. He has led the NFL in rushing three times (2008, 2012, and 2015), an NFL MVP award (2012), and seven-time All-Pro selections.
Peterson is nicknamed ‘All Day’ which is regularly shortened to ‘A.D.’
Peterson’s father gave him the nickname as a child because he was energetically active and could run all day long.
There is often confusion about Peterson’s nickname, where sometimes he is called ‘A.P.’ instead of ‘A.D.’, this is under the false assumption that his nickname is his initials.
