PFF: Top 25 O-linemen
 

https://www.profootballfocus.com/new...018-nfl-season

1. TERRON ARMSTEAD, NEW ORLEANS SAINTS
2018 Overall Grade: 89.4

Armstead has been in the conversation for best offensive lineman in the NFL ever since his breakout season in 2015 where he earned a 92.6 overall grade. He simply needed to stay on the field. While he’s been out since Week 10 with a pec injury, the left tackle was lights out enough in the first nine games to still earn this spot. In four of those games, he didn’t allow a single pressure.

6. RYAN RAMCZYK, NEW ORLEANS SAINTS
2018 Overall Grade: 83.4

The fact that the Saints have the highest-graded left tackle and second highest-graded right tackle tells you all you need to know about their offensive line. Ramczyk has had only three games all season where’s allowed multiple pressures.

I wonder how Armstead's injury history compares to the other guys on this list.
