The only games against upper power 4 programs that I could find include a 31-28 loss to Arizona in 2022 (Arizona 5-7 record); 23-21 win over Iowa 2016 (Iowa 8-5 was good win); 34-14 win over Iowa State in 2014 (Iowa State 2-10 record); 24-21 win over Kansas State 2013 (Kansas State 8-5 record); 37-24 win over Minnesota 2011 (Minnesota record 3-9); 6-3 win over Kansas 2010 (Kansas 3-9 record).
I will give them this, they have done well over the last 14 years mostly against teams in Iowa and Kansas, but they only play an upper level team about once ever two games, and I am sure they put everything into that game.
