I recall reading that the reason the officiating often goes in favor of the home team is because the officials (mostly subconsciously) are afraid of angering the crowd and having thousands of people boo them. Been shown with soccer fields where the crowd is closer to the field and therefor louder to those on the field, that the officiating is more in favor of the home team. Hard to fix unless you make them deaf.
“The player development is the main thing I like (about Michigan),” Williams said. “You can see that they develop their players. They get them in the gym and they work them hard. And their hard work pays off.”
