The Hawkeyes just finished maybe the most unexpected 12-0 regular season in college football history, and are playing for the Big Ten title and a spot in the College Football Playoff on Saturday night against Michigan State. But man, Iowa fans are excited.

That's impressive consumption. One would expect a bit of a late start after consuming that much suds, but Hawkeye fans bounced back strong to face the morning on the College GameDay set.

Nearly every sign behind the GameDay stage was pro-Iowa, and Hawkeye fans just keep on rolling.
