Big 12/SEC Challenge
The Big 12/SEC Challenge is an NCAA college basketball series that takes place in the middle of the season, usually late January, consisting of a series of ten games featuring members of the Big 12 Conference and Southeastern Conference. The format is similar to the ACC–Big Ten Challenge. Each of the ten members of the Big 12 plays a game against a member of the SEC. Half of the ten games are hosted by the Big 12 team and the other half are hosted by the SEC team. Because the SEC has 14 members , four teams of the SEC are excluded from the challenge each season. Effective with the 2019–20 season, the SEC teams excluded from the Big 12/SEC Challenge will participate in the newly launched SEC/American Alliance against teams from the American Athletic Conference. Previously, the Big 12 was a part of the Big 12/Pac-10 Hardwood Series from 2007 to 2010, and the SEC was a part of the SEC–Big East Challenge from 2007 to 2012. The contracts for those challenges were not renewed when they expired, leaving both conferences available to establish this challenge. (The issues faced by  the Big East in the 2010–13 Big East Conference realignment was a factor in the decision not to renew its series with the SEC). Two current SEC members, Texas A&M and Missouri, are former members of the Big 12. Missouri has a rivalry with current Big 12 member Kansas leaving the possibility of renewing the rivalry which has not been played in the regular season since Missouri left for the SEC. Team records through 2022 Challenge. Southeastern Conference (3–4–2). Because the conferences do not have the same number of members (SEC has 14, Big 12 has 10) four teams from  the SEC are excluded from participation each year. The number of times an SEC team is excluded is shown in the "DNP" column in the table above (updated to include 2020–21 challenge).
