Probably ku. We needed that win to clinch an NIT birth.

I would say it would have to be the @ ISU game in 96. Our last win vs a ranked team on the road is probably what got us to the dance that year.
Glancing at the schedules from the past, our last legit big game this late in the year was probably the 98 ku game. We had just won 4 out of 5 to get to 6-5 and #4 ku came to town to give us a shot at that marquee win we needed. We not only lost that one (big), we then lost at ISU and to OSU at home and finished 1-4 the rest of the way to fall to the NIT and got smoked at NC State.
