HOW IT WORKS:

Pro Football Focus, which nearly a third of the NFL subscribes to, has a complex grading process, looking at every player on every offensive, defensive and special-teams play. Plus or minus grades are given and are based around an average of 0, with each position graded slightly differently. If a player does something you normally would expect, then a score of 0 is given. Grades are given for plays that are reasonably considered to be better or worse than the average or expected play. For the final grade, player participation is factored in, using a normalization factor to set the average player in that facet of the game to 0.

Bears receiver Alshon Jeffery jettisoned himself into elite company in the league — fourth in receiving yards after Sunday’s games — with 12 catches for 249 yards and two touchdowns against the Minnesota Vikings. In PFF’s reviews, Jeffery, who now has 70 catches for 1,109 yards this season, had a season-best 5.1 rating on Sunday. He had success against any player assigned to stop him.

Defensive end Julius Peppers had 2.5 sacks against the Vikings and it was good enough for his second-best grade of the season, according to PFF.[iframe src=”//e.infogr.am/-6783775710500777″ width=”300″ height=”453″ scrolling=”no” frameborder=”0″]
