Childress was selected in the first round of the
1956 NFL draft by the
Chicago Cardinals. For his entire career, he played for the
Chicago Cardinals and
St. Louis Cardinals, primarily as a backup running back. He was known as an excellent receiver out of the backfield and a punishing blocker. His best season came in 1963 when he led the Cardinals in rushing and gained over 1000 yards from scrimmage while filling in for the injured
John David Crow. His best rushing game came on September 22, 1963, when he gained 136 yards on 22 carries against the
Philadelphia Eagles. Later in the season against the Eagles, he caught a 78-yard touchdown pass from
Charley Johnson. ==NFL career statistics==
