Unfortunately, the available replay evidence is somewhat conflicting.
1. The ball did not go over her hand (see the first picture)
2. The ball appeared to be close enough to her hand on the overhead shot that it almost had to have touched her
3. The ball doesn't appear to change directions
It's a tough call. I'm glad it went BYU's way. Several calls did not go BYU's way, but that's how it goes.
