Chiefs D too me still hasn't improved a whole lot vs the competition see Chargers, Cinci, Denver games.....I do agree Jones on the inside is better for the Chiefs but as you seen in the Pitt game they were doubling the center to help the guard with Jones and vs a team other than Pitt it has helped.
The way the o line for Buffalo has been playing I think you may see some of this as well but i think there are still issues that legit offenses are finding ways to attack them and do not think Buffalo will have issues, especially with the way the Bills have started to run the ball with Singletary it really is putting pressure on the opposing D
Biils just need to execute and I think they will get in the high 20's mid 30's
