Seems like an issue of recruiting transfers with multiple years of eligibility. That frontcourt was super crowded, so the freshmen weren't getting in off the bench, and it just gets worse with Sienna Betts joining. If Dugalic and Gardiner are both returning, then it makes sense to me for Barker to go elsewhere and start and put herself in a better position to be drafted.
Same with Londynn Jones (and Aarnisalo) and the backcourt. CLW will be available next year plus it sounds like they're recruiting Kneepkens.
