People always think it's a case of the better team overlooking the bad team. Still a long way to go but I never bought the "Bills win easy" narrative. People said the same about the Chiefs and Jets earlier this season, and so many other games. The Chargers have talent and are fired up with a ra ra coach and hearing people say how bad they are all week, plus last week they got humiliated.
This is the kind of game where if the Bills can get their noses in front early and then get a turnover, the Chargers will fall apart quickly. But as long as they're doing well they'll keep their heads up and keep playing hard
