I am sort of a college sports uniform snob, and a traditionalist, so I've liked looking back at some of the logos ISU has had in the past. Before we go any further though, in no part of the vast multiverse has the tigerhawk ever been merely "as" attractive (let alone less attractive) as any of ISU's logos.
Tigerhawk > ISU logos is a fixed point in all universes and timelines. I've checked............
With that said, I am never opposed to college teams sporting the best version of their uniforms. I've often argued that Illinois' classic Chief Illiniwek logo was among the best in all of college sports and that they should go back to the helmets they had in the '90s-'00s.
With Iowa State, I think this was a mid '80s uniform, and if they could find a way to just slightly modernize this look and add the "wavy" cyclone, as shown above, to the helmet, they would have top tier uniforms in the Big 12.
Those are Jim Walden uniforms. Started in 1987.
