Trevor Penning is PFF’s top graded Saint; Penning is highest graded NFL OT in Week 10

PFF grades are strange. Not only are the Saints OL not graded well this week but 3 of the Browns top 5 grades were DL on a day their defense gave up 216yds rushing and only had one sack.

Garret 82.8 - shut out statistically
McGuire 79.5 - (1) tackle
Harris 73.9 - (1) tackle

Like anyone watching film, they are making their best guess of what that player’s assignment was and grade the player based on that. If they were supposed to set the edge for the run and were successful, they get graded favorably even if others fail at their assignment and the offense gets a big gain.

According to their stats, Garrett had a few pressures and McGuire/Harris were credited with a few run stops (tackles where runner did not get a minimum yardage for the down/distance situation).
