Texas is at 15 scholarship players right now. Each of Coach Aston's recruiting classes is getting more talented than the prior one(s). So, if the newcomers are winning position battles and court time, that usually leads to returning players deciding they may want to move to a school where they can see more playing time; unfortunately, injuries and attrition are part of collegiate sports.
I have no doubts that the coaching staff knows exactly how to balance the roster and scholarships. I could see about 2 current players on the roster perhaps moving on after this season due to lack of playing time, and where they stand on the depth chart at their position.
Sara Hattis switched from volleyball to basketball scholarship this past summer; so, although a junior in hoops, she is a senior academically, and may have already decided that if she graduates next Spring that moving on to the next part of her life is best for her.
Most are assuming that Audrey-Anne Goudreau will be part of Texas' 2016 class after one season at a Florida CC/JUCO; we'll see for sure.
Appears Texas is still recruiting 2016 kids Ionescu, Chou, and Ciera Johnson. Signing a true Center like Johnson seems like the biggest need with Imani leaving after this season. But, so far, only Ionescu has publicized an upcoming official visit to Texas. I think Chou is headed to either UCLA or Berkeley; so, not really counting her coming to Texas.
