I feel like this would be a terrible choice for Texas. Bryanna Preston is the exact mold of PG that Vic likes and is waiting in the wings. They also have Booker who did an excellent job running point as a freshman. Hidalgo coming in and taking 15+ shots per game and running all over the court defensively doesn't fit in with Texas's style of play. Not to mention Texas is absolutely loaded next year on the wing and needs a pass first PG to distribute the ball.
Somewhat ironically, I think TCU would be a good fit for Hannah if she were to leave. Campbell can build the team around her, they have money to pay players well along with a couple of nice returning pieces in Hunter and Silva. Maryland and Ole Miss are other options too. Kentucky too with Tonie Morgan graduating.
