Everything you've all said makes perfectly good sense and as I think about your responses, most of them are spot on. I don't move forward when I'm stationary and I face the net. I'm actually not sure WHERE my feet should be when the ball comes right to me. If I don't have to move I don't. So my footwork is definitely an issue as well as the additional pressure. I love chasing balls down and it feels more natural. I guess I'm more relaxed in a way and not tight.
Thanks for responding, I appreciate the feedback.
