The Bills have a top Josh Rosen Jersey 10 offense while the Broncos' defense has been effective as of late. Stopping Allen will be important if they want to register another 'W.'

Diggs will certainly be someone Denver's defense will game-plan around, as he caught 10 pa ses for 130 yards and a touchdown against the Steelers.

That's the longest active cover streak in the NFL and it's tied for the longest cover streak in the NFL this season.
