waving hands in the face of a defender

[Hawks Coach]

Since the situation only refers to B2 not putting hands in front of A's eyes, it begs the question of whether or not the official believed that B1 had done so. B2 caught ball, but if B1 obstructed the vision intentionally, this is a darn good call. 10-3-8-d.

Since title is waving hands in face, it sounds to me like this is exactly what B1 did and was penalized for doing. But I can't tell because the original statement is not clear enough Ang.
