I do like ASU's kits, but they are their normal uniforms, not alternates. If Nebraska changed up their traditional kits similar to ASU, there would be mutiny. With an alternate, I think you push the envelope and set it apart from the traditional everyday uniform.
On a scale of simplicity and tradition: Nebraska --- three ASU kits mentioned above --- 2015 Nebraska alternate.
I wouldn't want Nebraska's traditional uniform or their alternates to skew towards the middle of that scale and be like ASU, while I do find them nice.
