Back in Fall 2018 (after the transfer portal was created) Iakopo and Rhoades announced they were transferring mid-year, and they were immediately eligible for the 2019 season.
Dolcini is not a first-time transfer. Even a grad-transfer who transferred once before as an undergraduate would need to submit a waiver request. Not sure if we have heard for sure. I mean, she's not even enrolled at Texas (yet) as she just graduated from Fresno State a few days ago; she did not participate in Fall ball at Fresno. Not sure when the waiver request can be officially submitted. I would have thought that Dolcini's reasoning would be that the prior head coach at Fresno was terminated for being verbally abusive to her players.
Dayton is a first-time transfer, but not a grad-transfer. There was an offseason head coaching change at Arizona due to Candrea's retirement.
