Nike does way to much neon and crazy stuff with their uniforms. Yes, the duct tape numbers were bad, but Nike did the gold numbers on a white uniform for FSU. Plus Oregon. Their uniforms are just... awful. Only ones that look good are the yellow and green throwbacks.
Nike will go as plain/oldschool/traditional as a client prefers (See USC and Alabama). Phil Knight uses Oregon athletics as a test bed for new materials, designs, and concepts as this is the arrangement he and his company have with the school. This is why Oregon rarely uses the same uniform more than twice.
