The NCAA punished BYU for observing the sabbath principles. They have steadfastly refused to put Thursday Saturday Thursday Saturday tourney sites in the west - and then forced BYU into demonstrably toughter seed than it deserved - because that is how the the Thursday Saturday Thursday Saturday sites back east were structured.
The only exception I can think of is Jimmers Senior year.
Don’t kid yourself - they have been unfair to BYU for years.
