Check out the numbers from the Atlanta-Oakland game. From CNNSI.com, second page:
Obviously Lane Kiffin was the problem in Oakland. If this isn't rock bottom for the Raiders, I can't fathom what it would look like otherwise. Not only was Oakland shut out 24-0 at home by the Falcons, the Raiders totaled just 77 yards of offense for the entire game -- their lowest total since 1961. Atlanta had 453 yards. And the Falcons owned decent advantages in both time of possession advantage (45:15 to 14:45) and first downs (30-3).
