The Ole Miss Defense should settle down and keep the Rebels in the game.
It'll all depend upon whether or not their Offense can start putting up some points. They need to put a little pressure on TCU; make them feel like they'll have to win a shoot-out in order to win. If they can do that and get TCU to press a little on Offense then the Rebels D will have some opportunities to make some big plays.
If Ole Miss is within seven points at the end of the first quarter, I like their chances.
