Below are grades for every Buffalo Bills player on every play in the team’s Week 12 win over the Jacksonville Jaguars. Efficiency Score, which debuted during the bye week, can be found on the furthest right column.
(For a quick primer on this project, this is from the introduction article. Here's a link to the entire thing.
"As I re-watch each game, I’ll be assigning number grades to each Bills player on every play this year, so keep in mind... the grades themselves will be inherently subjective. However, they should provide a relatively good idea of which players are struggling and excelling on the field. This system is not precisely how Pro Football Focus grades — they have multiple graders for each game and use a different numbering system — but it’s similar. Below you’ll find that grades were assigned in 0.2-point intervals on a scale from -1.0 to +1.0 on each play for each player."

Observations:
Tyrod Taylor -- Many Bills fans weren't happy with Taylor holding onto the ball too long, but remember, to make keep it as objective as possible, I only grade on the throws he does make. The bomb to Watkins was an absolute dime, as was he TD pass to Justin Hunter.
LeSean McCoy -- Not a transcendent performance, but not a bad effort either. Jacksonville routinely had eight -- and sometimes nine -- in the box, which limited the space for the Bills' runner.
Richie Incognito and John Miller -- Stud guards.
Cordy Glenn -- He struggled early, which was a bit surprisingly seeing as though he mainly faced off against a rookie pass-rusher, but he was more consistent in the second half.
Charles Clay -- Another strong effort as a blocker, which has become the norm. Minimal impact in the pass game though, which has also become the norm.
Ryan Groy -- Huge game from him. Routinely ontrolled interior defensive linemen in the run game and held his own as a pass-blocker.

Observations:
Jerry Hughes -- His proficiency as a pass-rusher has dipped lately but he was a monster stopping the run against Jacksonville. He shed blocks with ease, set the edge well, and closed quickly in backside pursuit often.
Marcell Dareus -- He truly is a run-game wrecker. Also, Dareus flashed some violent hand usage and impressive speed getting to Bortles on his sacks.
Kyle Williams -- On the Jaguars' opening drive -- which ended in a touchdown -- he was not effective whatsoever. After that, he was typical Kyle.
Jonathan Meeks -- His awareness as a free safety needs work, as evidenced on the Marqise Lee touchdown.
Corey Graham -- Deserves more recognition. He's durable and has been a solid run defender for a while now. He made a handful of impressive plays against Jacksonville.
Preston Brown -- Had his best block-shedding afternoon of the season. He's not as fast as Zach Brown, but if he continues to play aggressively against the run, he'll make a handful of plays each game.
