The final person who needs to shoulder a majority of the blame is offensive coordinator Ken Dorsey and the game plan he had. Entering his second season as a play caller, the hope would be to see improvements but it seems like more of the same from Dorsey.
A perfect example of this was the start of overtime and the Bills found themselves in negative down and distance right away with a false start by Spencer Brown. The first play call was a throw to Dawson Knox, which makes sense as the goal is to get into a more favorable down and distance.
However, the pass was incomplete and Dorsey tried to overthink it by running a draw play that would only net 3 yards. The Bills found themselves in 3rd and 12 and Allen was not able to connect with Stefon Diggs.
While the offense finished last year second overall in most offensive categories, it seemed like the leaague caught up to Dorsey and this group was not nearly as effective down the stretch. That trend has carried over into this season and the Bills have too much talent to only being able to muster 314 total yards and 16 points, regardless of the defense.
