"Unique" because during the period that the Cardinals were members of the Big East Conference, none of the Louisville athletic teams ever came to Dallas to play.
And next year, after UofL enters the ACC, the same will be true. But for this one season in the American Athletic Conference, the Cardinals basketball teams play home-and-home games with Southern Methodist University, and so it was that Shoni Schimmel, Antonita Slaughter, and the rest of the team came to Dallas.
The photoset below hopefully provides a bit of the flavor of the event for those who were unable to attend and a nice reminiscence for those who did. The Cardinals won by an 81-66 score.
