While I’m a firm believer of the concept of “any given Sunday” it’s also true that there is such a thing as a “should-win game.” The Buffalo Bills should beat the Denver Broncos. If they don’t it will certainly be called an upset. If that were to happen, what might be the cause?
It could be the defense. The depleted secondary, mild weather forecast, and what Josh Allen has done to better defenses already suggest that’s unlikely. Plus that answer is boring with their defense typically getting the credit. The more intriguing avenue for an upset is the volatility of their passing game.
