Still was selected by the
Chicago Cardinals in the 16th round (145th overall pick) of the
1948 NFL draft but did not play for the Cardinals. He instead signed in January 1948 with the
Los Angeles Dons of the
All-America Football Conference (AAFC). In August 1948, the Dons traded Still to the
Buffalo Bills. He played for the Bills during the 1948 and 1949 seasons, appearing in 21 AAFC games. He was on the team when the Bills advanced to the
1948 AAFC Championship Game against the
Cleveland Browns. He and
George Ratterman were the first quarterbacks to play in a championship game for the city of Buffalo. He went 6-of-18 for 80 yards with a touchdown and two interceptions in the 49–7 loss. ==Family and later years==
