Jeff Sagarin's rankings of the nation's top programs by decade in the "ESPN College Basketball Encyclopedia" nicely track the history of the rivalry. In the 1950s, when the rivalry was at its peak, Kansas State finished the decade ranked as the #3 program in the nation and KU was ranked as #4. In the 1960s KU was ranked #9 for the decade and KSU was ranked #11. In the 1970s, the programs were again nearly even, with Kansas State ranked at #24 and KU at #25. In the 1980s some separation appeared, as KU finished the decade ranked at #19 and Kansas State at #31. The big difference appeared in the 1990s and 2000s when KU was ranked at #4 and #2 for the decades, while Kansas State does not appear anywhere in the top 40.
