Recent WNBA draftee Loryn Goodwin from Oklahoma State went to 4 schools. Started North Texas with Karen Aston, then Aston left for UT before she suited up, but was Sun Belt Freshmen of the Year. Then transferred to Butler, but that coaching staff was let go after some claims of verbal abuse arose before she suited up. She said the new coaching staff played a style of offense that didn't mesh with her skillset, so she then transferred to UT-San Antonio, where she became Conference USA Newcomer of the Year, and applied for an extra year of eligibility and was granted it but UTSA did not have her chosen masters major after graduating so she transferred to Oklahoma State, where she won Big-12 Newcomer of the Year and was 1st Team all Big-12.
That's the most prominent and recent four school player I could think of.
