He we go. This series, starting with #0, will continue throughout the Re-Loading Season. It is my hope that it will inform, entertain, and create some debate among Broncos fans about different guys that have worn different numbers. In some cases, there will be no debate because a number was only worn by one person. That is the case with #0, who saw just one season of activity in a Broncos uniform.

The Greatest Denver Bronco To Ever Wear #0 - John Olszewski, FB -- 1962

Johnny 'O' Olszewski was an All-American Running Back at CAL from 1949-1952 before being drafted with the 4th Overall pick in the 1953 NFL Draft by the Chicago Cardinals. Johnny O played for the Cardinals from 1953 – 1957 earning Pro Bowl honors in both 1953 and 1955 and Western Conference first team honors in 1956.

After being dealt to the Washington Redskins in 1958 Johnny O became the ‘Skins primary back for three seasons and was first and only player in Redskin history to wear the number "0". In 1961 Olszewski played for the Detroit Lions before finishing his career with the Broncos in 1962, helping the Broncos to a 7-7 record, easily their best season in the 60's.
