We used to play them every year in the 70's and 80's, UK used to beat the crap out of them and it was like playing Ole Miss, I mean one year Darnell Valentine and KU blew a win against Macy and D. Anderson, it was a joke of a series. I remember Larry Brown beating UK I think, I know Kenny Walker beat them in Louisville. Roy beat Pitino his first year awful, Self beat Tubby in elite 8 game. Overall UK has beat their tails.
Think Rupp died when UK was playing KU. Those games were not that special until the last few years.
During the 70's and 80's, the KU game was really not even considered a big game, it wasn't
Growing up in the 70's the big games were IU, UT, LSU, Alabama, Notre Dame. UL wasn't on schedule yet, the SEC teams rotated but those were the big one's. Arkansas came on board in 90's and UL in 80's
UNC and KU are teams you want to beat due to pedigree but for most part not that much interest.
