I would think that an announcement this quick shows that she's been upfront and open with the staff. For those questioning the timing, what did you want? Did you want her to announce in June? As for announcing during the year, I don't blame her for not wanting the distraction.
I found it really interesting that during the men's Big 12 tournament game against OSU, the announcer talked about an odd interaction he had with Phil Forte. Essentially, and I'm paraphrasing, the announcer had asked him if he was wanting to go play overseas, and in response Forte gave him a look and made a comment hinting that he was ready to be done playing basketball.
I think we have it in our heads that these kids only live for basketball. But to feel the need to get up every day in the off season and lift, condition, shoot, and then to have all that plus film study during the season would get tiring. I can't blame someone for having priorities beyond basketball such as health and career.
