Theodore Joseph Marchibroda was an American professional football player and head coach in the National Football League (NFL). He played four years in the NFL as a quarterback with the Pittsburgh Steelers and Chicago Cardinals (1957). He was later head coach of the Colts in two different cities and decades, first in Baltimore during the 1970s and then Indianapolis during the 1990s. Upon joining the Baltimore Ravens in a similar capacity in 1996, he became the only individual to serve as head coach with both of Baltimore's NFL teams and gained the unusual distinction of having three stints as an NFL head coach for two franchises in two cities, but with no two of those tenures being for the same franchise in the same city. His career coaching record was 87–98–1 (.470) and 2–4 in the playoffs.

The Baltimore Colts were a professional American football team that played in Baltimore from 1953 to 1983, when owner Robert Irsay moved the franchise to Indianapolis. The team was named for Baltimore's history of horse breeding and racing. It was the second incarnation of the Baltimore Colts, the first having played for three years in the All-America Football Conference and one in the National Football League (NFL). This Baltimore Colts played their home games at Memorial Stadium.
