Teams, by defensive yards per play conceded:
Memphis: 6.68
Ole Miss: 6.00
Vandy: 5.57
Kentucky: 5.79
Teams we played against in OCT:
LSU: 4.49
UGA: 5.26
Bama: 4.68
USC: 5.40
So the worst defense we played against in September is still better than the best defense we'll play from here on out. USCe provides a similar situation to what we'll see against Kentucky. USCe is very good against the run (#11 in the country) and are very weak against the pass (#105). Kentucky has a statistically good pass defense (#12). They have, however, a very weak run defense (#91). If, against Kentucky, we can get our running game going and don't commit turnovers... we win.
We can go 4-0 in November if Bray progresses well and we stay healthy. However, I think we end up going 3-1. I don't think our defense can stop Kentucky's offense and I don't think Bray can keep up in a shootout.
