I think the Bills defense will be better. They weren't very good last season and I expect them to be somewhere around 10-15 this year. Not great, but able to do enough to win some games. I think what you take away from pre-season is if they look like they know what the hell they are doing. Last season...didn't necessarily get that feeling. This season, they at least seem to have some idea that they are supposed to stop the other team from advancing the ball down the field.
