I think the fact that Saniya was a bit out of control of herself/the ball when contact with defense started to be made is what made it a good no call. She was off balance/fumbling the ball before contact because William made a great defensive recovery and appeared to establish position. Saniya tried to adjust to this, but because she had committed to the drive down the (apparent) open lane, then lost her balance trying to avoid a possible offensive foul; she then tried to heave up a prayer...it was about all she could do given no obvious pass options due to the overload of offense/defense on the right side. About 100% of the time, no matter what time of the game that a situation like that occurs, refs will eat the whistle.
