Nothing good can come from naming names here and questioning credentials. Obviously he was qualified to work this level, and as I'm sure he'd admit, made a very wrong call. The R1 is an excellent referee who has worked multiple men's and women's final fours and is an international referee. I'm sure they both feel way worse than the teams involved, but it's not a good idea to make a bad situation worse, especially with people in our own fraternity, by pointing out the people involved.
Just my opinion.
