I have been a HUskt fan since 1968 snd I want to know why?

During the Notre Dame game, why did the Huskies take the field with the wrong number of players 3 times?? DAAAAAH

Against BYU why didn't the Husky coach get thrown out of the game challenging the refs call to add 15 yards to the extra point try. I learned in high school that the peenalties after a TD are always added on the kick off!!!! DAAAAH
