(B10 is upright, facing and no hands). W15 makes a moved to her right and her left foot caught B10's planted foot and W15 goes down.
B10 was in, what I thought was, a classic legal guarding postion. Feet were shoulder width, and hands and arms about 30 degrees down to her side. W15 made her move before B10 could react, thus B10 was still planted... both feet.
The action was right in front of W Coach. In fact when W15 fell, she was about 8' from W Coach. W Coach said nothing.
I really thought I'd get more grief from the first no-call.
