Heard this and thinking of all those wins Johnny had against OU, Mizzou and KU at Hilton and Fred's season's, I didn't believe it. Would have figured there was more.
It does seem like we’d have more than three vs. No. 1, but maybe some were top 5 and are just mashed into memory as being ranked higher.
A few I found ... I didn’t do a thorough search or for each year, mostly from the Orr seasons:
KU in ’84 was unranked
KU in ’85 was #10
KU in ’86 was #4
OU in ’86 was #5
KU in ’87 was #15
KU in ’88 was #16 (ISU was #15)
Missouri in ’89 was #3
KU in ’92 was #3
OSU in ’92 was #2
(at) KU in ’05 was #2 (the Stinson teardrop shot)
(Missouri in ’83, the “Birth of Hilton Magic” game, was “only” #10)
