I can see your point. Personally, I just want stuff to look good; the year the idea was created notwithstanding. The two specific ones I called out were these, though:
One is straight-up modern, the other one has more old-school elements (i.e. shoulder loops and gray facemask). For me, though, the color balance is off. Arizona has multiple shades of red. An aforementioned "amazing" Boise state look has an okay jersey/pants with a unbalanced helmet that I really don't like. But then you have other uniforms that are modern and look really good.
Again, it's about balance, not modern vs old
