No. It doesn't. A three point home advantage is the average from the field. It isn't a set figure. LSU, and Bama, both have a very low home field advantage. The reason is they win both on the road and at home by about the same margins. It's a very common misconception on what home field advantage means in points. Homefield advantage compares performance against expected scores at home AND on the road to quantify the value of playing at home. The advantage a team gains at home (relative to opponent) is applied in the opposite direction on the road (data independence is treated similarly for inputs). In June the rankings were released on NCAA D1 teams home field advantages. Both LSU and Bama ranked among the lowest. It opened, depending on casino, at Bama -7 and -8. They feel there's a touchdown difference.
