When the Big Ten split into East and West divisions, there was much time and energy spent thinking about protected crossovers games and the frequency with which teams played each other. At the time of the change (2014), Iowa and Penn State had just taken their first year off since 2006. In the 13 years prior, Iowa had won 8 of 11 meetings between the two teams. Shortly after the realignment, Iowa and Penn State was back to being an annual game, but Iowa’s edge was gone.
Penn State has now won the last six meetings, including every game since Joe Paterno left the program, and Iowa hasn’t won in the last decade.
