‘Everywhere you look on the Buffalo Bills’ roster, there are question marks. Can a rebuilt offensive line protect the quarterback? Can any receiver step up and be a legitimate second option behind Kelvin Benjamin? Can Nathan Peterman be a viable starting quarterback, and if not, is rookie Josh Allen ready? Defensively, who is going to provide a pass rush? Can Trent Murphy and Vontae Davis stay healthy and contribute? All of that amounts to a level of uncertainty that makes it impossible for me to predict a second straight playoff appearance.’
