I like A&M quite a bit, and I like them because I think they are motivated to win big for Manziel. Duke is solid but not great on both sides of the ball. Defense has been A&M's bugaboo this season, and has kept them from winning and covering several games this season. That, of course, is the concern for A&M backers in this game, but I honestly think after playing SEC West competition all season, Duke's offense will be a notch or two below what A&M is accustomed to seeing. I think A&M will get their points, but I also think we'll see a surprisingly good defensive performance from A&M.
I will also be on the 1st half UNDER for much of the same reason.
Duke will probably hang tough for a half, but in the end I think this is a very one-sided game.
