The WNBA is a tweener season in the US while most of the players then play a full season internationally. It is trying to grow, but growth is spotty and their marketing is strongly targeted at women and girls since they have been the heart of their fan base so far.
I think Baylor is a better place to develop as a coach, and note that many of the WNBA coaches have been NBA players that appear not to have progressed in the NBA coaching ranks (thinking specifically of Bill Laimbeer.)
I wish her the best for Baylor's sake. Have quite a few cousins and friends who went there. Surprised they didn't have a sit down with Mulkey and iron out differences. But at some point it becomes easier to hire someone more compliant regardless how good.
