To call this football game on Saturday the biggest game for each team is not much of a stretch.
The Iowa versus Iowa State rivalry dates back to 1894, but the two teams did not play each other from 1934 to 1977, the year the Cy-Hawk Trophy was established.
Throughout the 71-year history of the game, Iowa holds the all-time lead 47-24, but Iowa State has won two of the last three.
The No. 72 game in the series takes place at Jack Trice Stadium in Ames, Iowa, as both teams enter the game with undefeated records.
