1 - I think that with the benefit of super slow motion replays from a variety of angles I've got a travel before the contact/ enough contact to be more then incedental.

2 - In real time trying to jusge impending contact and evaluate the level, I'm probably not as glued into the feet. Based on the amount of contact there ended up being and the fact that I wasn't sure on footwork until I got both angles means I'm going foul in game and afterwards looking at tape admitting the tape shows something a little different.

These were my feelings, which is why I posted the video.

When I watched the play live, i.e., the first angle, my first thought was 'Whoa...it looks like she shuffled there." Your thoughts in point #2 were my thought process as well. Not saying I'd be kicking myself for calling the foul but it was pretty close.
