Keep in mind the way these odds work. If you see odds that are too pessimistic, you can make money off the house. If you see odds that are too optimistic, then you can't really do anything about it.
Thus, generally speaking the house has an incentive to make overly optimistic odds. This is especially true early on when there is a lot of publicly available information out there that the oddsmaker hasn't had time to really process and "do his homework" on. Once all the preseason articles and depth charts and rankings come out, expect the odds to move in the direction of LSU having a slimmer shot at a 2013 BCS national title (which is not a 2014 title, by the way, even though the title game will be played in January 2014).
