I have no horse in the race, as they say, so I'm just guessing like everyone else.
Perhaps she wanted to be close to home, but did not get any D1 scholly offers. This seems a good choice for her to continue her education but still get to play hoops and improve her game. Perhaps after 2 years, she will get some D1 offers she's interested in.
All speculation of course. But that seems logical to me. Then again, there could be numerous different reasons none of us are aware of. Maybe she will address it in an interview - given the huge interest UCONN fans have in all our players, even when they transfer, it would be nice if someone on the horde would do a zoom interview with her and ask the questions!
