But a 79 rating seems a bit harsh.
So does this: an 89 for Darius Slay. That places him ninth among cornerbacks, coming off his second straight trip to the Pro Bowl. He's the only player in the NFL with at least 30 passes defended and at least 10 interceptions over the last two seasons.
After Slay, Detroit's top five is rounded out by defensive end Trey Flowers (87) and wide receivers Marvin Jones (86) and Kenny Golladay (83).
Another apparent snub? Kerryon Johnson, who ranks 33rd among running backs with an 81 rating. Before he got hurt last season, Johnson was one of the NFL leaders in yards per carry.
Detroit's first-round pick tight end T.J. Hockensen is tied for fourth among rookies with a rating of 77.
Four players across the league received a 99 rating this year: Aaron Donald, DeAndre Hopkins, Khalil Mack and Bobby Wagner.
