Our memories of the same era could not be more different. For starters, I recall precisely zero conversation regarding Miami's "flamboyant" uniforms. They had two unis - one home and one away - just like everyone else at that time.
Nobody wanted to emulate Miami's "braggart stylings." On the contrary, rules were created to specifically to stop them. The only thing other fans envied was Miami's undeniable athleticism. In short, the anology you are going for - that Oregon is the new Miami - is baseless. Oregon has more in common with Nebraska than Miami (eg, bottom half of the 50 states in terms of population, very little competition from pro sports).
I haven't heard anyboy suggest we should change our colors to orange or green. We are talking about adding a couple of altnernate unis that woud give the kids something to get excited about. And if you think the appeal of the alternate unis is limited to some bizarro subset of "flashy" athletes, watch the Ohio video where the new jerseys are introduced.
