UCLA is losing Barker, Jones, Aarnisalo and three other freshmen to the portal. It actually make sense to Barker. Sienna Betts will take a lot of playing time in the front court. If Dugalic does not leave, that means less time for Barker. Aarnisalo is good enough to start on most teams. So she would not want to be backup for another year.
UCLA is currently one of the four finalists for Kneepkens. If she comes, that means less playing time for Jones.
