I don't remember the game as it is just before my first OU hoops memories, but I have heard people talk about what a great game it was for the Sooners. I'd love to see some clips but haven't been able to find any. Any time we beat KU in a high profile game is definitely worth seeing again.
The only video I can find from that era is the 1988 NCAA final and the last second loss to UNC in the 1990 tournament.
