‘There isn’t one specific thing that’s gone wrong in the red zone, or if there is, the Bills aren’t saying what it is. Players and coaches have given the standard “we have to execute better” line to explain the struggles, although Stefon Diggs shed some light on it when asked Wednesday why the team hasn’t been able to reach the end zone more consistently: “Things do get tighter down there and with things being tighter, routes got to be crisper, throws got to be tighter – there’s going to be smaller windows. You’ve got to work as a unit. At the end of the (Tennessee) game, I feel like we didn’t help ourselves. We could have done some things differently, especially at the wideout position.”’
