Looks like the Hawkeyes are unveiling a throwback uniform to honor their 1921-22 squad. Presumably, these will be worn against Iowa State, but if they get critical acclaim I could see them being worn in late November when Nebraska comes to town.
Also, on the uniform front, West Virginia has unveiled an all-gray look. Ugh. Since they're joining the Big 12, I hope they play Oklahoma State in the Cowboys' gunmetal duds. Would bring a whole new meaning to Dust Bowl.
