Not a game in Norman, but I think my favorite OU/KU game was the Big 12 CG in 2002. OU won that one 64-55 against the #1 team in the country. OU was #4 at the time. That KU team was LEGIT. Tons of talent. That is still one of the best defensive games I've ever seen a team play. Jabahri Brown straight up dominated Collison and Gooden (I think) inside. KU couldn't do anything that day. KU had 19 points in the first half.
