scheduling the game when BYU was in Hawaii. They knew well in advance that BYU would be in Hawaii for that tournament. They then had to scramble and fix things after releasing the original schedule. "Fixing" things involved BYU playing USD twice in a row.
It's not something BYU asked special accommodations for. It would be like if the WCC scheduled Gonzaga to play USF yesterday after knowing Gonzaga had a game at Southern methodist.
