It has become apparent this offseason that Pro Football Focus is a big fan of the Raiders' offensive line. Earlier this offseason they said the Raiders will rival the Cowboys for the best offensive line in football. And if you look at the individual grades they have on those linemen, you can see why.

Getting some love most recently is Rodney Hudson, who they have tied for the best pass blocking efficiency in the league along with, of course, Cowboys center Travis Frederick.

Best pass-blocking efficiency among NFL centers in 2015:



t-1. Travis Frederick, DAL

t-1. Rodney Hudson, OAK

3. Stefen Wisniewski, JAX — Pro Football Focus (@PFF) May 21, 2016

Along with rating the Raiders offensive line at least on par with the Cowboys, Hudson's 84.7 rating was highest among the entire starting five. And he did it despite being hobbled by an injured ankle much of the latter half of last season.

Also interesting is the third name on the list -- Raiders former center, Stefen Wisniewski who spent last season in Jacksonville and signed with the Eagles this offseason where he could be switching to guard. Wiz was selected by the Raiders in the second round of the 2011 draft and is the nephew of Raiders former All Pro guard, Steve Wisniewski.

Hudson's topping this list also says that PFF is a big fan of the Raiders 2015 free agent class as a whole. Earlier this week Dan Williams was listed as having the third best run stop percentage in the league among defensive tackles.

The do not, however, grade fellow 2015 free agent addition Malcolm Smith very highly, though I think Smith performed better than their grades suggest mainly because he never left the field and played inside and outside, replacing Curtis Lofton who was absolutely a failed free agent addition.
