here's an error that needs to be fixed... the helmet color changed in 1984, not 1987, which was well after Ferguson was traded

Buffalo Bills Uniform: 1987-2001
In 1987, the helmet's background color was changed from white to red. Bills quarterback Joe Ferguson was color blind, and thus the change was made to help him distinguish them more readily from three of their division rivals at that time, the Indianapolis Colts, the Miami Dolphins, and the New England Patriots, who all also wore white helmets at that point.[4] (The Patriots now use a silver helmet, the Colts have since been realigned to the AFC South, and the New York Jets, who wore white helmets until 1978, have since switched back to white helmets.)
