 For several decades in the 20th century, Oregon's uniforms were traditional, generally featuring a yellow helmet (with the original interlocking "UO" emblem) and yellow pants, joined with a green home jersey with gold letters or white road jersey with green letters and "UCLA-style" shoulder loops.During the Jerry Frei era (1967–1971), the helmets were solid green with subtle logo variations.In 1972, new head coach Dick Enright returned the yellow helmet with Green Bay Packer-style green and white striping and no logos, a helmet style that continued until 1977, when new head coach Rich Brooks added the green block-style interlocking "UO" emblem.
