If Memphis can hold down their offense, I'm certain we can. The only difference is that we will have a much easier time scoring.
It's easy to have a good looking defense when the most prolific offense you've played is a mediocre Boise St team (yes, I'm aware that Memphis has a higher ranked scoring offense, but they ran up 63 on Austin Peay... who is horrible even by FCS standards).
By the time Ole Miss figures out much of anything on offense, we'll already have a decent lead. Alabama 45 - Ole Miss 10
