I think the coaching staff realized that the talent and experience level was just not good enough. I'm not sure Walker is a game changer but she will help the depth a lot. I agree we are lacking in the post also. Vaughn is a nice player but not ready for prime time yet. Cosgrove is a female Luke Zeller and will never be comfortable underneath the basket unless they can transform her body.
I think we will difinately see the return of the pure Princeton offense next year! Beat em with execution and not out-talent em.
Personally I think and hope you are mistaken about Vaughn. As long as she maintains her health, she will be a force to be reckoned with. Cosgrove I am not as optimistic about,
