The 3.5-4.0 was not a betting line. You have made the same mistake before.Once Vegas sets the opening line, the flow of money alters the line..
Each alteration is a separate pool
The way the line is moving indicates that more money is flowing in on Notre Dame, but Vegas felt that ND was a 3.5-4.0 favorite.
The fact that Vegas had ND at less than the touchdown favorite, concerns me.
USC it’s always a challenge at home
