PSU was annual from 81-92. They dropped us when joined Big 10. GATech had been sporadic - not sure we played them once between 81 and 97 and only 2005-6 before ACC thing. Pitt was great 70s 80s games. UNC rare. Thing I like about MSU and Purdue was proximity and familiarity with their teams, history, coaches, players, fans - road trips to away games very easy esp for students. Great tailgaters home and away. ND travelled well there and Vice versa even in bad years for either or both teams. I don’t think Wake, Duke, Louisville etc replace them well.
