The Pitt coach used a really questionable challenge earlier in the 5th set, asking for a net violation on Stanford. It was unsuccessful so I don't believe he had a challenge available for Rubin's hit on match point at 11-14. I was ready to turn off the game when the back referee signaled that it had gone long. Point Pitt, match over, Pitt starts to celebrate. But wait!! The up referee signaled a touch. Point Stanford. Not challenged. Play on. 

Then I think it was at 13-14 that Pitt was called for a violation that I did not entirely understand. The announcers tried to explain in the moment that it was something not allowed by a back row player. Can anyone elaborate?
