Hayman devoted five decades of his life to football in Canada. As a 25-year-old in 1933, he coached in his first of five Grey Cup victories, as Toronto edged Sarnia 4-3. Hayman was a perfect 5-0 in Grey Cup games as a head coach, including the Alouettes’ 1949 victory. He coached the Alouettes for six seasons, compiling a 37-33-2 regular-season record and a 4-2 playoff mark.
He was inducted into the Canadian Football Hall of Fame in 1975.
