2017 Minnesota Vikings Pro Football Focus grades.
Before we get started I would like to make some things clear about PFF grades.
Pro Football Focus (PFF) has been grading NFL players since 2004. The football analytics site evaluates individual performances on a play-by-play basis. On every play of every game, a PFF analyst will grade each player on a scale of -2 to +2 according to what he did on the play.
From the Pro Football Focus website:
The grading method was designed to build a clearer picture of how players performed, rather than simply judging performances based on box-score stats. Stats can be misleading.
While most statistical analysis is quantitative in nature, PFF uses qualitative measures and opinion-based grading as the basis of their rankings, so like baseball umpires, their calls could be construed by critics as “biased.” However, the grading process is overseen by at least three individuals per contest, so while the numbers may not always be perfect, the process itself is rather reliable.
What’s also unique about PFF is that season-level grades also account for the duration of good and bad play, resulting in “compounded” grades (both positive and negative) if the player’s performance continues for long periods of time. Basically, the grades factor in “streaky” play. Kinda cool, right?
Anyways…I hope that helped. It’s better to know these things beforehand because some grades may surprise you.
So without further adieu, here are the 2017 season grades for each qualified Viking. The players are arranged by grade within their position group. Notable position rankings are listed in parentheses.
