The offensive line might be an afterthought to the casual NFL fan, but that is not the case with NFL front offices. They put a premium on edge protectors in this pass-happy NFL.
Here, we take a wide-angle look at the available offensive linemen on the free-agent market this winter.
This list focuses on the top 10 free-agent offensive linemen who are in their prime. So, you will not see Carolina Panthers left tackle Jordan Gross (pictured above) here, despite the fact he earned a 33.5 rating from Pro Football Focus. That is the top grade among all of the free agents, but he is also near retirement at the age of 33.
Because statistics are hard to come by for those who make their living blocking, we use PFF's widely accepted ratings system throughout our analysis in this 10-part slideshow.
