Admittedly, I don't watch volleyball replays frequently. I did see the "double pinky" frame also. But I also saw other fingers/or thumb double frame too, including on the hand that wasn't near the ball. Unless the referees has some other camera angles or super duper slow motion to provide irrefutable evidence, they had no business reversing the call on the floor. We played poorly after it was called and score was 13 -11 them. We'll never know if the outcome would have been different if we went forward from a 12 - 12 tie.
It's so ironic that we got reffed (as somebody else called it) with two blown calls that changed the outcome of the Michigan at Illinois 2000 football game from a win to a loss. That incident was the catalyst for the B1G to implement football video replay, and eventually all of the NCAA to adopt it. Then we got reffed in 2013 NCAA basketball tournament on a blown out-of-bounds call that awarded Miami possession in the final minute and potentially decided the outcoume. Video replay showed, and Miami player later admitted, they touched last but rules didn't allow video review of out-of-bounds calls. NCAA created new rule allowing video review on out-of-bounds calls in the last 2 minutes of games. Now, in 2018, we get reffed in a Women's Volleyball Final 4 game with a blown video review call. I wonder what "new" NCAA video review rule will come out of this?
