If you are putting the Bills inadequacies on offense on the offensive line, you are looking in the wrong direction. Scheme and poor playcalling at opportune times have been the issue. Drops have also been a huge issue through most every game. Protection has not been perfect, but you will probably note that one player left out of the statement you are quoting is Cody Ford. While improved, a lot of QB pressure was coming directly from that side of the line.
