Agree, they would look terrible with cardinal jerseys and helmets.
Regarding the gold pants, they probably wouldn't look great, but we should do a c/c/g. What's the harm? We had that look pretty much from the 2008 - 2016 set (the USC look). Let's just see it again in the present uni set. We had gold pants the first year of Chizik also, 2007 (included cardinal jerseys with white numbers).
My opinion, for what it matters - 1. There isn't much gold in the helmet or jersey, so it won't look great, but it also wouldn't be horrible, see 2007. 2. Most of us got tired of the c/c/g look from 2008 - 2016. 3. The majority of ISU fans don't think the present mustard gold looks good in the FB uniform pant or helmet. The present coach certainly feels this way. 4. It will probably get me jump started on working to complete my darker gold mocks. I think ISU really needs to add a darker gold, even if just for the FB pant and any potential future FB helmet, keep the present gold for most everything else, if they wanted.
But, you have to think we will see the gold pants at least once this year? Why order them otherwise? We will be wearing c/w/g, or w/w/g against Utah. That's my prediction anyway.
