and ACC. The Big 12 lost members to the SEC, the Pac-12, and the Big Ten, while the Big Ten also gained one former ACC member. The remaining members of the Big East split into two conferences: the American Athletic Conference (the American) and a new Big East Conference that does not sponsor football (only three of the original 10 members of the current Big East sponsor football, all at the second-tier Division I FCS level). The American, the football successor to the Big East, is no longer considered a power conference. Despite the major conference realignment from 2010 to 2014, relatively few schools dropped out of or joined the ranks of the power conferences. Two of the three non-AQ schools that had appeared in multiple BCS bowls left the Mountain West Conference and joined a power conference, as Utah joined the Pac-12 and TCU joined the Big 12. Former Big East members Temple, Cincinnati, and South Florida are all now part of The American; another former Big East member, UConn, left American Conference football after the 2019 season to become an FBS independent while otherwise joining the current Big East. Of these, only Temple was a founding member of the Big East in football. The most recent major realignment is currently ongoing. During a period of less than two months in 2021, the Big 12 both gained and lost members. First, on July 30, the conference lost two of its mainstays when Oklahoma and Texas announced that they would leave for the SEC no later than 2025. The Big 12 reloaded by announcing four new members on September 10, initially announcing that American members Cincinnati, Houston, and UCF plus FBS independent BYU would join no later than 2024. BYU's initial announcement stated that it would join in 2023, and the other three schools' 2023 entry date was officially confirmed after they reached a buyout agreement with The American. On June 30, 2022, Pac-12 mainstays UCLA and USC announced they would move to the Big Ten in 2024. At present, six of the nine former members of the Southwest Conference are in Power Five conferences: Arkansas and Texas A&M are members of the SEC, while TCU, Baylor, Texas, and Texas Tech are members of the Big 12. Houston and SMU are members of the American, with Houston now set to join the Big 12 in 2023, while Rice is a
