Post Player Drills

I am starting to work with a post player and its been a while since I played. I'm just wondering what you feel like the most important things to teach her are and what I should focus on the most. I have got a bunch of post play moves that I will be working on, but if you have any other ideas I'd greatly appreciate it.

Spend lots of time on footwork and aggressiveness. This book does a great job answering your question in much more detail.
