I'm pretty sure she was implying that her daughter was in a dark place mentally in that situation, hence why she left the team midseason. Rickea herself said that she still had love for the school so I doubt she was dissing the school.
I get this as well. Rickea seemed like she loved MSU, she easily could have left the minute Vic bolted for Texas but she stayed (she played 3 seasons at MSU). She could have gone to almost any program in the country, she was a top 10 recruit for a reason. The program has been through a lot over the last few years, lots of changes in coaches, the pandemic, off the court drama with Carter, etc.
She didn't seem very happy to me (as someone who watched her body language) towards the end. I think she really tried but thought a change would probably be in the best interest for her. I don't think she ever got much better since her freshmen season but going through all these coaching changes, COVID and battling things mentally definitely took a toll.
Hopefully she can find a place where she will be happy and in a better place mentally.
