You do realise the majority of takes on here are Josh is an issue, but isn't the sole problem? Just as Dorsey isn't the sole problem, McDermott isn't a sole problem, receivers dropping the ball isn't the sole problem, other players showing ill-discipline by gifting opponents penalties isn't the sole problem. But put them all together and we are where we are.
If Josh had played better the Bills would have beaten the Pats. If the defense hadn't let the abysmal Pats defense put up 29, the Bills would have beaten the Pats. If Murray hadn't driven into Pats defender on the Knox TD, the Bills would have won. The issue is everything is a mess at the moment - it goes beyond one player or one area.
