THAT is the issue. From what I have seen they largely prove to be incompetent.. ignorant.. or a complete non-factor... which means they are afraid to throw deserved flags.
They could have brought them along slowly.. let them climb through the ranks... or find some trans-female refs who played the game.
I have an idea.. how about making a crew of ALL female refs and see what happens. let them do the Texas-Oklahoma game or Michigan-OSU or USC-UCLA.. let the whole nation score them on their collective quality.
