Don't be surprised to see the Big12 beat up on each other SEC-style. Texas, Ok-St, OU and TTech all have way too difficult a schedule to not lose somewhere along the line (OU would endure a 2nd loss). Texas looks great now, but it only takes one poorly played game and the dream is over.
Your 2 big games to keep an eye on are: Ohio State upsetting Penn State. Florida beating Georgia next week (and winning out from that point on). Other than that, I would think LSU would have control of their own destiny.
