He had previously led UMass in 1996 and Memphis in 2008 to the Final Four, but those appearances were later vacated.

From 1982 to 1985, Calipari was an assistant at the University of Kansas under Ted Owens and Larry Brown. From 1985 to 1988, he was an assistant coach at the University of Pittsburgh under Paul Evans. From 1988 to 1996, he was head coach at the University of Massachusetts. From 1996 to 1999, he was head coach and Executive VP of basketball operations for the NBA's New Jersey Nets. During the 1999–2000 season, he was an assistant coach for the Philadelphia 76ers under coach Larry Brown, before moving on to his next position at the University of Memphis. He was inducted into the National Italian American Sports Hall of Fame in 2004.

In his 21 official seasons (22 seasons overall, 21 official, with one entire season later being vacated) as a collegiate head coach, Calipari's record is 548–171 (.762). His record in the month of March is 98–37 (.726). His record in the NCAA tournament is 38–13 (.745), and in the NIT is 15–6 (.714). His teams have made 14 NCAA tournament appearances (12 official, due to 2 later being vacated), including reaching the Sweet Sixteen 11 times (9 official, due to 2 later being vacated), the Elite Eight 9 times (7 official, due to 2 later being vacated), the Final Four 4 times (2 official, due to 2 later being vacated), the NCAA Championship Game twice (once officially, with the 2008 Championship Game appearance while at Memphis being vacated by the NCAA), winning the NCAA Championship at Kentucky in 2012.
