Two of those wins were against the #1 seeds in both conferences and that can’t be ignored especially considering the Ravens lost to both the Eagles and Chiefs. Those were high profile games as the Chiefs would he playing for undefeated legacy right now otherwise.Allen has been great with his team but:
The Bills have beaten up on porous teams. The AFC East literally has 3 below .500 teams. Bills play them 6 times. This season they also facing the AFC South which has another 3 teams below .500 teams. So that's 9 games against below .500 teams. And of course, they beat below .500 and battered 9ers, making it 10 below .500 teams
Facing winning record teams, has resulted in an average output for the Bills (3-3). Including a 35-10 route put on them by Baltimore
The quality of teams are just much lower and statistically Lamar is much higher.
If you want to disregard that loss due to it being week 1, then you could essentially do the same for that Bills loss being early in the season.
