Born in Gatineau, Quebec, Francois rose to prominence as a member of the Quebec Major Junior Hockey League's Laval Titan. He was drafted 152nd overall by the Buffalo Sabres in 1986 following two less-than-inspiring seasons in the QMJHL. but then he blossomed with 129 points and 144 points in the following two seasons in junior hockey.
Guay, no relation to former Los Angeles King and US Olympian Paul Francois Guay, turned professional in 1988-89 and really struggled. He got into just 45 games and scored 6 goals and 26 points with the Rochester Americans.
A healthy Guay emerged as a credible AHL player in 1989-90. He impressed enough with his 28 goal, 63 point season to warrant a look at the NHL level. Little did Francois know then that that would be his only NHL game.
Francois returned to Rochester for the 1990-91 season but was unable to improve his game to the point where he would be given another shot in Buffalo.
A free agent in the summer of 1991, Francois found very few offers to his liking. He opted to try playing in Europe for year. It turned out to be a great move for Francois, who really enjoyed his year in Innsbruck (Austria) and returned for two more years. Ultimately Francois would continue playing in Europe through the turn of the century. He would star in both Switzerland and Germany.
