Jules Yakapovich (1921–1993) was an American football coach and former NFL player for the Detroit Lions.
[1] Born in Tonawanda, New York, he served during World War II as a U.S. Marine Corps lieutenant.
Yakapovich was head football coach at Kenmore West High School in New York from 1950 to 1976.
His undefeated 1969 team was named number-one in the state by the New York State Scholastic Writers Association[2] and chosen number-one in the nation by the Junior Super Bowl Committee, which at the time published the principal national ranking of high school football.
Yakapovich devised the all-standing "radar defense" in which a defender's initial movement is lateral, rather than forward or backward.
