Tennessee hired Marshall coach Kim Caldwell on Sunday, going outside the Lady Vols family for the first time since the late Pat Summitt stepped down in 2012.

Caldwell replaces Kellie Harper, who was fired last week after five seasons coaching at her alma mater. Caldwell will be introduced at a news conference Tuesday. The move might be considered outside the box to some. Both Harper and her predecessor, Holly Warlick, had deep ties to the program.

Tennessee parted ways with coach Kellie Harper on Monday after five seasons, opting to make a change to try and reinvigorate a program that has not played for a national championship since the late Pat Summitt retired.

Harper, who played under Summitt, could never quite get the program back to an elite level. Though she won 20 or more games four times, Tennessee never advanced past the Sweet 16.

"After a thorough review of our women's basketball program, I have informed Kellie we are making a change in leadership," Tennessee athletic director Danny White said in a statement.
