I think the Bills offense was outschemed from play one onward, so I can't argue with this. I actually thought Taylor played well overall, akin to the besieged troops at the Alamo. He had no chance on so many of those sacks, and many of those sacks were a product of a better scheme on the defensive side. Dennison did not attack the five-man fronts with quick passing designs until way too late. I'd put turnovers higher because they arguably cost the Bills 6 points on offense and 7 points on defense (they lost by 13 points). The first two fumbles were lost in FG territory, and Taylor's fumble (essentially garbage time, but still) led to 7 points for the Jets.
By the way, Leonard Williams is a monster. He is the best player in that draft as judged per the position he plays (that is, I'd still take a qb over him): https://en.wikipedia.org/wiki/2015_NFL_Draft. He is basically unblockable.
