A look at PFF's offensive line ratings

The Jacksonville Jaguars' offensive line has been the second-least effective in the NFL per the review and grading of Pro Football Focus' Khaled Elsayed.

The site’s current grades for Jaguars offensive linemen: Eugene Monroe +12.8, Uche Nwaneri -1.8, Mike Brewster -2.7, Herb Taylor -2.6, Cameron Bradfield -4.3, Brad Meester -8, Guy Whimper -8.8, Eben Britton -10.9.

Not pretty.

Only Arizona's line, regarded by many as among the all-time worst, rates as worse.

The Colts are 27th, with a mention for OK pass blocking (led by a 10.9 by right tackle Winston Justice) but poor run blocking that includes a positive rating for only left tackle Anthony Castonzo.

The Titans are 19th, and left tackle Michael Roos (10.0) is praised for a return to his typical, solid form. Unfortunately for Tennessee, he had an appendectomy on Monday and may not be able to play. The interior three get poor marks.

The Texans are just 13th, and PFF says the rotations at right guard and right tackle are evidence of the shaky play of Antoine Caldwell (-7.2) and Derek Newton (-8.9.), Duane Brown is the highest-rated left tackle in the league (18.3).
