They had three starters on their D line out with injury. Not sure what you expected from backups and practice squad guys pretty much off the couch. And their crappy D line made a great tandem play to further turn the game around.
Cincy has a terrible time defending TEs. First play - 32 yards to a TE. Why throw to WRs when the TEs were open all day. All three would have had TDs if Knox hadn’t bobbled it.
Both Cincy and Dallas have a franchise QB and two elite WRs. Neither will make the playoffs, in all likelihood. The Bills have done a great job weathering the storm of injuries every year; since Allen arrived, the Bills have done well getting decent performance from their backups after injuries.
I swear people read the takes in these threads but don’t pay attention to what’s actually happening here and around the league.
