I'll Be Back! Schools Come Full Circle Returning to Old Stomping Grounds

Dominoes seem to fall every time a school seeks greener pastures. The Ivy League is the only Division I conference to remain intact since the late 1980s.

Oddly, some schools such as Boise State (Big West), Charlotte (C-USA), Georgia State (Sun Belt), Idaho (Big Sky), Pacific (West Coast) and San Diego State (Big West) are going full circle and returning to leagues where they previously were members. They join the following institutions that re-enlisted with a conference after leaving for various durations:
