<human>: Wilbur Charles "Weeb" Ewbank (May 6, 1907 - November 17, 1998) was an American professional football coach. He led the Baltimore Colts to NFL championships in 1958 and 1959 and the New York Jets to victory in Super Bowl III in 1969. He is the only coach to win a championship in both the National Football League (NFL) and American Football League (AFL).

Shortly after graduating from Miami in 1928, Ewbank took his first coaching job at Van Wert High School in Van Wert, Ohio, overseeing the football, basketball and baseball teams. He remained there until 1930, when he moved back to Oxford and took a position coaching football and basketball at McGuffey High School, a private institution run by Miami University. He also taught physical education at Miami. Ewbank took a break from coaching in 1932 to pursue a master's degree at Columbia University in New York City and filled in as Miami's basketball coach in 1939 after the previous coach left for another job, but otherwise held his coaching positions at McGuffey until 1943. Under his tutelage, the school's Green Devils football team had a win-loss record of 71-21 in thirteen seasons. This included a streak of three undefeated seasons between 1936 and 1939 and one season - 1936 - where the team did not allow any scoring by opponents.  Ewbank joined the U.S. Navy in 1943 as American involvement in World War II intensified. He was assigned for training to Naval Station Great Lakes near Chicago, where Paul Brown, a former classmate who succeeded him as Miami's starting quarterback, was coaching the base football team. Brown had become a successful high school coach in Ohio before being named head football coach at Ohio State University in 1941. At Great Lakes, Ewbank was an assistant to Brown on the football team and coached the basketball team.  Following his discharge from the Navy at the end of the war in 1945, Ewbank became the backfield coach under Charles "Rip" Engle at Brown University. He also was head coach of the basketball team in the 1946-47 season, his only one at Brown.  Ewbank's next stop was as head football coach at Washington University in St. Louis for the 1947 and 1948 seasons. Ewbank guided the Washington University Bears to a 14-4 record in two seasons. The team had nine wins and just one loss in 1948. CANNOTANSWER
