Professional career
McQuay skipped his senior season to sign with the Toronto Argonauts of the Canadian Football League in 1971. Though small, at and, he had lightning speed and was known as "X-ray". He took the CFL by storm, rushing for 977 yards and a 7.1 yard per carry average. He was an all star and runner up for the CFL's Most Outstanding Player Award. Unfortunately, his most famous, or infamous, moment came in the 59th Grey Cup versus the Calgary Stampeders. Toronto fans had waited decades for a champion, and with less than two minutes left, down by 3 points and on the Calgary 7-yard line, quarterback Joe Theismann handed off to McQuay, who promptly slipped on the wet turf and fumbled away the ball; Toronto lost. The fumble was actually the result of McQuay hitting the turf without being touched. The contact with the ground dislodged the ball causing the fumble. Unfortunately for the Argos this was allowed within the rules at that time. Subsequently, the rule was changed such that the ground was not allowed to cause a fumble. He rushed for 745 yards in 1972, but the Argonauts' fortunes faded. Coach Leo Cahill would say "Leon slipped and I fell." In 1973, he saw limited playing time and was traded to the Calgary Stampeders. McQuay was picked by the New York Giants in the 5th round of the 1973 NFL Draft. He would go on to play 13 games for the Giants in 1974, 13 games for the New England Patriots in 1975 and 4 games for the New Orleans Saints in 1976, mostly returning punts and kickoffs. His best year was 1974, when he rushed for 240 yards. McQuay would return to Toronto for the 1977 season, rushing for 307 yards. He also played for the Jacksonville Firebirds of the American Football Association in 1980 and was drafted by Tampa Bay Bandits of the United States Football League in 1983, but was cut before playing with the team. After retiring, McQuay returned to his native Florida to study to become a Minister, but died unexpectedly of a heart attack in 1995, aged 45.
