I nearly forgot that this weekend's game against Iowa State is the throwback game honoring the 1921 and 1922 teams. It looks like some students put together a site as part of a class. Go there to learn about the two undefeated team and purchase a throwback uniform for yourself. They're only like $600.

Oh, and here's Iowa official picture of the uniforms. I think they look sharp.
