I actually liked the red facemask -- I loved the red/white/white of the Kansas game. I would favor that as a "permanent" change, particularly if we ditch the non-school color jerseys and pants. I just hate non-white monochromatic looks. It looks like a leotard, not a football uniform.
No reason we should ever wear an element that is not cardinal, gold, or white. Ever. You can do enough and plenty of cool things with just those three SCHOOL colors if you want to.
I would not say that Oklahoma State's uniforms are "clean" whatsoever, and they mix-and-match odd combinations and alternatives so often, as well.
This is a clean, classic Oklahoma State...
Which they do sometimes in their new set, yes...
But you see a lot of gimmicky "sheriff" nonsense from them, too...
Gray is not a school color of theirs, and the little "wing" stripes on their shoulders are stupid.
I will shut up if we trend more towards the first sort, but I imagine it is probably going to be a mixture of both (at least) if not having some gimmicky base set with way too many alternatives.
