2007–08 Memphis Tigers men's basketball team achieved a No. 1 ranking in the Associated Press basketball poll in January 2008, the school's first No. 1 ranking in the poll since 1982, and went on to win their third straight Conference USA title on March 15, 2008. After a month, they lost this ranking when they were defeated by in-state rival and No. 2-ranked Tennessee at home. Led by First-Team All-American Chris Douglas-Roberts and future No. 1 overall pick Derrick Rose, the team received a No. 1 seed in the 2008 NCAA tournament and defeated No. 16 seed Texas-Arlington in round one, No. 8 seed Mississippi State in round two, and No. 5 seed Michigan State in the Sweet Sixteen. Memphis convincingly defeated No. 2 seed Texas in the Elite Eight round to advance to the school's first Final Four since 1985. Following this win, Memphis went on to beat No. 1 seed UCLA on April 5, 2008, advancing to the National Championship game on April 7, 2008. With this win, Memphis became the first team in NCAA history to achieve 38 wins in a single season. After holding a nine-point lead with two minutes and 12 seconds left in regulation, the Tigers lost to Kansas in the National Championship in overtime by the final score of 75–68, becoming the second NCAA runner-up team in Memphis history. The 2008–09 Tigers, led by another freshman guard, Tyreke Evans, again went undefeated in Conference USA and earned a two seed in the 2009 NCAA tournament. The Tigers were defeated by the No. 3-seed Missouri Tigers in the Sweet Sixteen. Evans left after one year and was named NBA Rookie of the Year in 2010, the second straight Tiger to do so after Rose. On March 31, 2009, Calipari resigned to become the head coach at the University of Kentucky.

The recruits included Xavier Henry, DeMarcus Cousins, Nolan Dennis, and Darnell Dodson.
