Methodology
What are Impact Ratings?
These ratings are my attempt to assign a single numerical value to each player’s performance in the NFL, using the metrics listed in each position’s formula.
The grading scale is 0 to 100, with 100 being the highest possible score and 0 the lowest. Obviously the ratings aren’t perfect, but I feel I can get a good evaluation from these numbers.
Tiers
| 85–100 | Elite Starter |
| 75–85 | High Level Starter |
| 70–75 | Above Average Starter |
| 65–70 | Below Average Starter |
| 55–65 | Low Level Starter |
| 40–55 | Backup/Replacement Level |
| 0–40 | Should not be on the field |
