NFL Week 9 grades: Jaguars get an 'A+' for shocking upset of Bills, Cowboys get an 'F' for blowout loss

Here are the Week 9 grades for each team

Bills quarterback Josh Allen has been one of the most unstoppable players in the NFL this year, but it seems he does have one weakness and the name of that weakness is Josh Allen. 

This isn't a story about some internal conflict that the Bills quarterback might be having, it's a story about how Jaguars defensive end Josh Allen helped his team engineer a stunning 9-6 win over the Bills, which will go down as one of the biggest upsets in recent NFL history. 

With both offenses struggling, this was a game where the winner was going to need their defense to make a big play and that's exactly what Allen did for the Jaguars. In one of the most dominant defensive performances of the season, Allen recovered a fumble, picked off a pass and recorded a sack and the Jags needed every bit of that to pull off the stunner.
