Yesterday, the Ravens turned in a nail-biting 13-19 loss to the Broncos. The team looked sloppy on the field, especially the offensive line. The team's performance is reflected in some pretty embarrassing grades from Pro Football Focus. If anything, this is just confirmation of how bad the team's offensive line was yesterday.
Check out that last box. 20 of Flacco's 32 attempts were under pressure. That's not good at all.
This is perhaps the most telling of all the metrics. Just look at where the linemen fall on this chart.
Curious what PFF grades are?
PFF's grades represent the most recent momentum of a player, or as they put it, "our rating is how good a player is right now." The grades are "represented through a 1 to 100 scale and [we] use a weighted depreciation over the past two years with more weight given to recent games." The green represent an uptick in performance, while red means the opposite.
PFF relies on a handful of analysts grading each and every play on a scale of -2 to 2, with -2 being a very bad play, and 2 being a very good one. For more info on PFF's grades, they can explain here.
