Here are the final Pro Football Focus (subscription required) ratings for the Detroit Lions in 2015.
This is how the Ratings are interpreted and read:
| Grading Scale | ||||
| 0-59 | 60-69 | 70-84 | 85-59 | 90-100 |
| Replaceable | Backup | Starter | Pro Bowler | Elite |
Using that scale, the Detroit Lions had a pretty bad squad. They might have overachieved going 7-9 considering the lack of talent on the squad.
| Starter Rankings | Pathetic | Below Average | Average | Pro Bowl | Elite |
| Offense | 4 | 3 | 3 | 1 | 0 |
| Defense | 1 | 1 | 8 | 1 | 0 |
| Under Contract in 2016 | Pathetic | Below Average | Average | Pro Bowl | Elite |
| Offense | 4 | 3 | 3 | 1 | 0 |
| Defense | 4 | 1 | 5 | 1 | 0 |
The Detroit Lions had two Pro-Bowlers in reality, but they do not match-up with who Pro Football Focus assigned a Pro-Bowl grade to. Calvin Johnson and Ziggy Ansah made the actual Pro-Bowl, but the Darius Slay and Calvin Johnson were the only ones to grade out as worthy.
