SC has some small LB's and a young and depleted secondary. I think A&M puts up more than 21.
I don't have much faith in the defense for obvious reasons but if they can create some turnovers (forced or unforced) then I think that will be enough to keep A&M in the game until the end.
First thought is playing a game of this magnitude the first game of the year is a disadvantage for A&M but I'm not sure how you can truly gauge that. I think there are a lot of unknowns here that could come into play. For that reason, I will take the 10' points Vegas is giving A&M.
