The Buffalo Bills haven't started a season at 4-1 since 2011. As analyst Matt Sabuda points out, that year slipped away quickly as the team finished at 6-10. Sabuda sees greater possibilities ahead provided the team addresses some inefficiencies. At the top of that list is the decision-making of quarterback Josh Allen. The Bills are 8-1 in games when Allen throws one or fewer interceptions; when that number rises to two or above, the Bills are 1-6.
