I wish we had detailed data as to what sacks and pass rush in backfield were totally the fault of the O-line. I know Ford struggled a lot and maybe only Morse is above average but play calling and play design also have to be considered.
It drives me nuts when the Bills run an empty backfield on 3rd and 3. First of all, you take away the unknown of pass vs run. Second, if someone misses an assignment or just loses their battle, there’s no back to cover up. Now Singletary was a rookie and is small, but he likely wouldn’t be useless back there. Even a chip of the rusher before going out on a pattern would help.
