Well something happened. She actively had been recruiting in the portal and clearly had been planning on next season. Either something came up within the last week or she was told to step down or be fired. If it was the latter, its a bit of weird timing unless they have a good hire in place. Next season is a blimp in the scheme of things as long as they get the hire right.
It felt like she lost a lot of fire as a coach after she had her first child years ago to many. Maybe stepping away from coaching (like the articles have alluded to) means she would like to do something that could allow her to do more with her family. This is a tough profession that requires a lot of time committed to it between recruiting, traveling, practices, community service etc.
