Worst of the worst: PFF hands out gruesome Bills' grades from loss to Bears

After suffering through his team's ugly — even historic — 38-0 loss to the Chicago Bears last Sunday night, Buffalo Bills' head coach Sean McDermott surmised that the performance "was not up to our standards."

Bills Mafia wholeheartedly agrees. And now we that the analytics brains at Pro Football Focus concur as well.

Considering the way the Bills were dominated on both of the ball in the preseason blowout, it would be fitting if McDermott and PFF just graded the team with a collective 0.0 and moved on toward Saturday's exhibition finale in Tampa and the Week 1 regular-season opener Sept. 7 against the Baltimore Ravens.

If we're being honest, the secondary was shredded by both Bears' quarterbacks Caleb Williams and Tyson Bagent.

Other than one nice catch by Tyrell Shavers, it was a wholly forgettable night at Soldier Field.

We could single out the missteps by safeties Cole Bishop and Damar Hamlin and ... let's just allow PFF to present its ugly truth: the lowest-graded Bills vs. the Bears. Remember, 100 is a perfect score. Ouch.

3. QB Mitch Trubisky: 49.1

Hard to fathom his play was worse than White's, but ...
