Duke and Kansas are set to face off in a rare on-campus basketball matchup on Sunday. The last time Duke played at Kansas' Allen Fieldhouse was in 1988. These high-profile exhibitions offer teams a chance to compete at a high level without affecting their records. They also generate significant revenue, with games often sponsored and broadcast by major companies. Kansas coach Bill Self emphasizes the importance of these games both on and off the court. Despite not counting toward official records, such games carry pride and legacy for both teams, especially Kansas, which recently lost an exhibition to Louisville.
