They have been almost invincible at home.
Part of that is that they have played a lot of bad teams at home.
Most of those have been MWC teams. Mix in some weak non-conference opponents like Idaho, Idaho State, Louisiana Tech, etc. Their toughest opponents have been some P5 schools but most of those have been bottom enders like Oregon State, Washington State, etc.
They have a small number of quality teams mixed in to there but very few.
