I know the rules won't allow a ref to overturn a call that they make during the game. That being said, if Oturu makes the free throws to tie and then Minny wins it in overtime that would have been a crime. I would like each coach to have a challenge. You probably would hang on to it just for situations like Luks's last foul with the game on the line. I suppose if that rule was there then you would have to hope the refs can see they missed it and correct it. I thought Oturu simply lost his footing and went down and a ref thought he saw a push. I didn't see it.
