The Oregon uniform underwent a radical change for the 1999 season, where new, Nike-designed gear featuring a redesigned "O" emblem with solid green helmets and jerseys with lightning yellow letters were revealed. This began a period of unusually non-uniform standards for a typical college football team. Since 1999, Oregon has completely revised its uniform appearance roughly every three seasons. The frequent uniform changes and their typically flashy uniform have provoked some controversy. Fans of a more traditional approach to college football tend to ridicule each new uniform as it is released, while younger fans and players—in particular, potential Oregon athletes—react more favorably to the flashy nature of the livery.
