George Kay Stephenson (born December 17, 1944) is an American former college and professional football player and current coach, whose latter career has seen him work in four different professional leagues. Stephenson played quarterback for the American Football League's San Diego Chargers and Buffalo Bills. He finished his career in the World Football League playing for the Jacksonville Sharks in 1974 before entering the coaching ranks.
After serving as a quarterbacks coach the previous season, Stephenson succeeded Chuck Knox as Buffalo Bills head coach on February 3, 1984. Stephenson was reportedly surprised to get the job, claiming that Bills owner Ralph Wilson "never explained his reasons for selecting me." Under Stephenson, the Bills went 8-8 in 1983, 2-14 in 1984, and after losing the first four games of 1985, Stephenson was replaced by Hank Bullough. Perhaps the most lasting impression that Stephenson left on the Buffalo Bills was when he decided to change their helmet color from white to red prior to the 1984 season, insisting that the change would aid Buffalo quarterbacks in finding receivers downfield. At the time, three of the Bills' four division rivals (New England Patriots, Indianapolis Colts, and Miami Dolphins) wore white helmets. The gambit didn't work as interceptions actually increased the subsequent season.
