While I'm generally skeptical of anonymous sources, assuming that there is some truth to the rumors about DD leaving TN, regardless of my thoughts about the Lady Vols, I hope for her sake that she does not go through with it. My first thought is that this is a young person that had an emotional reaction to a bad situation.
When DD surprised everyone by announcing she was returning for a 5th year, the reasoning was fairly straightforward. She wanted to be the player, leader and teammate that everyone hoped she would be from the time she first stepped on campus at Chapel Hill.
If she leaves now, it will be an act of petulance and immaturity that will damage any effort for DD to establish her "brand" after college, and it will follow her for the rest of her life as the player who abandoned not one, but two teams.
Hopefully, the adults around her, HW, her father and others, can persuade her to stick it out.
