I’ve graded every Buffalo Bills player on every single offensive and defensive snap this season, and it’s now time to put those grades to good use.
Which player has made the most of his time on the field? In other words, who’s the most efficient? Which player hasn’t made much of an impact despite playing a lot of snaps? Who’s not very efficient?
Efficiency Score (ES) formula:
[overall grade / number of snaps] x 100
*I’ve multiplied everyone’s score by 100 simply to get bigger, whole numbers.

Thus far, the average ES for a Bills offensive player is 1.15. (*min 50 snaps)
- Average ES for OL = 2.05
- Average ES for skill-position players = 1.65
Here are the players with the five highest and five lowest Efficiency Scores on offense (min. 50 snaps):
| Offense | Snaps | Efficiency Score |
| Jerome Felton | 149 | 4.69 |
| Mike Gillislee | 155 | 4.25 |
| LeSean McCoy | 430 | 4.04 |

Notes:
-- Given the Bills' run-game prowess, it's pretty fitting and not surprising that Jerome Felton, Mike Gillislee, and LeSean McCoy have the highest ES on Buffalo's offense.
-- After Jordan Mills, Eric Wood has the lowest ES of the starting offensive linemen (+0.54).
-- Cyrus Kouandjio has a strong ES of +3.31 on 145 snaps.
-- Robert Woods (+1.46) and Walt Powell (1.44) have an almost identical ES.
