Through four games, the Buffalo Bills find themselves as one of the lone two teams remaining unbeaten. The Bills are the only AFC team that is 4-0, and the other team in the league that remains undefeated is the Philadelphia Eagles. As October approaches, there is one main issue that the Bills have; their defense.
Buffalo is allowing six yards per carry on defense and the only team that has given up more rushing yards is the Chicago Bears, but by only one yard (658 yards to 657 yards). As the weather starts to cool down and the physicality of the game picks up, the Bills must fix the run defense somehow and someway.
